Help Me To Improve My Application Performance
Mar 13, 2007
Dear Experts,
I'm a DBA, Working for a Product based company.
We are implementing our product for a certain client of huge OLTP.
our reports team is facing problem (error: all the reports are timed out).though the queries are written properly, Each query is taking some minutes of time.
I've given the command DBCC DROPCLEANBUFFERS.
the time immediately dropped to 10 sec.
now my question is :
please suggest me the DBCC commands or any DBA related commands to improve the performance of the application for my reports team.
Thanks in advance.

Hi,
We have a poorly performing SQL 2000 db. i have just defragged ( the HD, not indexes, these are done daily via SQL Agent) the data files of our server and have not found any improvement in response.
I have now got into using SQL profiler to analyse the server performance. in the results that the trace is returning there are some huge (REALLY BIG) values for the duration and cpu values but these rows have no textdata value returned (ie it is null)
why is this? for these rows, the reads and writes columns are also high.
if these rows are what is taking the cpu's time then how can i identify what the server is doing to make any changes?
any thoughts on what other values i might trace or what action i can take to find the slow down cause?
in performance manager the processors (dual Xeons) are rarely dropping below 60%.
thanks in advance

Hi All,
from your experience in SQL 2005 - do i have any free software that can help in improve performance or can help in identifying performance bottleneck. two examples of performance and help that i use usually use are the maintenance plan that do (check DB > reorganized index > rebuild index > update statics) and the second software is the SQL 2005 DASHBOARD for the reporting help.
do you have any other free tools and help that you can give me for performance or any thing that i must have in my SQL 2005 servers.
Thx

I have a table called work_order which has over 1 million records and acontractor table which has over 3000 records.When i run this query ,it takes long time since its grouping bycontractor and doing multiple sub SELECTs.is there any way to improve performance of this query ??-------------------------------------------------SELECT ckey,cnam,t1.contractor_id,count(*) as tcnt,(SELECT count(*) FROM work_order t2 WHEREt1.contractor_id=t2.contractor_id and rrstm=1 and rcdt is NULL) as r1,(SELECT count(*) FROM work_order t3 WHEREt1.contractor_id=t3.contractor_id and rrstm=2 and rcdt is NULL) as r2,(SELECT count(*) FROM work_order t4 WHEREt1.contractor_id=t4.contractor_id and rrstm=3 and rcdt is NULL) as r3,SELECT count(*) FROM work_order t5 WHEREt1.contractor_id=t5.contractor_id and rrstm=4 and rcdt is NULL) as r4,(SELECT count(*) FROM work_order t6 WHEREt1.contractor_id=t6.contractor_id and rrstm=5 and rcdt is NULL) as r5,(SELECT count(*) FROM work_order t7 WHEREt1.contractor_id=t7.contractor_id and rrstm=6 and rcdt is NULL) as r6,SELECT count(*) FROM work_order t8 WHEREt1.contractor_id=t8.contractor_id and rcdt is NULL) as open_count,(SELECT count(*) FROM work_order t9 WHEREt1.contractor_id=t9.contractor_id and vendor_rec is not NULL) asAck_count,(SELECT count(*) FROM work_order t10 WHEREt1.contractor_id=t10.contractor_id and (rtyp is NULL or rtyp<>'R') andrcdt is NULL) as open_norwoFROM work_order t1,contractor WHEREt1.contractor_id=contractor.contractor_id andcontractor.tms_user_id is not NULL GROUP BYckey,cnam,t1.contractor_id ORDER BY cnam*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!

Hey guys,Here's my situation:I have a table called lets say 'Tree', as illustred bellow:Tree====TreeId (integer)(identity) not nullL1(integer)L2(integer)L3(integer)....L10(integer)The combination of the values of L1 thru L10 is called a "Path" , andL1 thru L10 values are stored in a second table lets say called'Leaf':Leaf====LeafId (integer)(identity) not nullLeatText varchar(2000)Here's my problem:I need to lookup for a given keyword in each path of the tree table,and return each individual column for the paths that match thecriteria. Here's the main idea of how I have this now.SELECT TreeId,L1,L2,...,L10, GetText(L1) + GetText(L2) as L2text + ...+ GetText(L10) AS PathTextINTO #tmp FROM Tree //GetText is a lookup function for the Leaf tableSELECT L1,GetText(L1),L2,GetText(L2),...,L10,GetText(L10) FROM #tmpWHERECharIndex(@keyword,a.pathtext) > 0Does anyone would know a better,smart, more efficient way toaccomplish this task? :)Thks,

SQL Experts,
I'm facing a performance issue with the following query...
The Output of the following Query is 184 Records and it takes 2 to 3 secs to execute the query.
SELECT DISTINCT Column1 FROM Table1 (NOLOCK) WHERE Column1 NOT IN
(SELECT T1.Column1 FROM Table1 T1(NOLOCK) JOIN Table2 T2 (NOLOCK)
ON T2.Column2 = T1.Column2 WHERE T2.Column3= <Value>)
Data Info.
No of records in Table1 --> 1377366
No. of distinct records of Column1 in Table1 --> 33240
Is there any way the above query can be rewritten to improve the performance, which should take less than 1 sec...
(I'm using DISTINCT because there are Duplicate records of Column1 inTable1 )
Any of your help in this regard will be greately appreciated.

I am not an expert in either SSIS or VFP technology but know enough to get my way round. One anomaly I did discover I thought was worth sharing for all those concerned with getting large amounts of data out of VFP in as short a time as possible. When you search for performance tips in relation to SSIS the advice is to never use select table or view from data access mode list in ole db source as this effectively translates to select * from table and I've never come across anything to contradict this €“ well I am and let me explain why:
When you use SQL command as data access mode in ole db source (where ole db source is foxpro dbc) and you write out select column1, column 2 etc etc from table a etc etc and then connect that to a destination (in my case ole db destination) the SSIS task spends ages stuck on Pre-execute before anything happens (the bigger the fox tbl the longer the wait). What is happening behind scenes is that the foxpro engine (assuming its foxpro engine and not sql engine €“ either way don€™t think it matters too much) is executing the sql command and then writing results to a tmp (temp) file on your local temp folder €“ (in my case : C:Documents and SettingsautologinLocal SettingsTemp1). These files take up gigs of space and it is only when this process is complete does the SSIS task actually finish the Pre-execute and start the data transfer process. I couldn€™t understand a) why my packages were stuck on pre-execute for such long times? and b) why were the tmp files being created and why they were soo big?
If you change from SQL command in source to Table or view and then select your table from list the SSIS task when executed kicks off immediately and doesn€™t get stuck on pre-execute nor create any tmp files €“ so you save time and disk space. The difference in time is immense and if like me you were really frustrated with poor performance when extracting from VFP now you know why.
Btw maybe this does not apply to all versions of VFP but it certainly does to v7.

Hi,
I have database D1 which contains 5 million users and one more database D2 having 95k Users.
i wanted to insert common users into new database D3 based on filter which is Phone number and is unique value. Below is the structure of my tables in D1 and D2:
D1(database)
UserProfiles(Table)
UserId (Column Name)
UserProfiledata (Column Name)
D2 (database)
Alerts (Table)
PhoneNumbers (ColumnName - Unique)
Now userProfiles table contains data in string format as below:
User.state AA User.City CC User.Pin 1234 User.phonenumber 987654
so iam parsing for each user using cursor and writing phone numbers into some temp table and wanted to query D2 database to verify whether this phone number exists in Alerts Table of D2 database.
can anyone please suggest on how i can go ahead with this and also help me on how to improve perfomance.
Thanks,

Hi everyone
I need a solution for this query. It is working fine for 2 tables but when there are 1000's of records in each table and query has more than 2 tables. The process never ends.
Here is the query
(select siqPid= 1007, t1.Gmt909Time as GmtTime,(t1.engValue+t2.engValue+t3.engValue+t4.engValue) as EngValue,
t1.Loc1Time as locTime,t1.msgId
into #temp5
from #temp1 as t1,#temp2 as t2,#temp3 as t3,#temp4 as t4
where t1.Loc1Time = t2.Loc1Time and t2.Loc1Time = t3.Loc1Time and t3.Loc1Time = t4.Loc1Time)
I was trying to do something with this query.
But the engValues cant be summed up. and if I add that in the query, the query isnt compiling.
(select siqPid= 1007, t1.Gmt909Time as GmtTime,
t1.Loc1Time as locTime,t1.msgId,(t1.engValue+t2.engValue+t3.engValue+t4.engValue) as engValue
--into #temp5
from #temp1 as t1
where exists
(Select 1
from #temp2 as t2
where t1.Loc1Time = t2.Loc1Time and
exists
(Select 1
from #temp3 as t3
where t2.Loc1Time = t3.Loc1Time and
exists
(Select 1
from #temp4 as t4
where t3.Loc1Time = t4.Loc1Time))))
I need immediate help on that, I would appreciate an input on it.
Thanks

When I query the view with a column (that is indexed in both tables) in the where clause, it's taking taking 3 Minutes to give the result. The column is of DateTime data Type. Any ideas as to how to improve the query performance ???

Hello,
I have the following setup and I would appreciate any help in improving
the performance of the query.
BigTable:
Column1 (indexed)
Column2 (indexed)
Column3 (no index)
Column4 (no index)
select
[time] =
CASE
when BT.Column3 = 'value1' then DateAdd(...)
when BT.Column3 in ('value2', 'value3') then DateAdd(...)
END,
Duration =
CASE
when BT.Column3 = 'value1' then DateDiff(...)
when BT.Column3 in ('value2', 'value3') then DateDiff(ss,
BT.OrigTime, (select TOP 1 X.OrigTime from BigTable X where X.Column1 >
BT.Column1 and X.Column3 <> 'value4' order by X.Column1 ))
END,
FROM
BigTable BT where BT.Column3 = 'value1' OR (BT.Column3 in ('value2',
'value3') and BT.Column4 <> (select X.Column4 from BigTable X where
X.Column1 = BT.Column1 and X.Column3 = 'Value1'))
Apart from the above mentioned, there are a few more columns which are
just a part of select statement and are not in any condition statments.
The BigTable has around 1 Mil records and the response time is very
poor, it takes around 3 mins to retrieve the records (which would be
around 500K)
With the Statistics ON,
I get the following:
Table 'BigTable'. Scan count 2, logical reads 44184, physical reads 0,
read-ahead reads 0.
Table 'WorkTable'. Scan count 541221, logical reads 4873218, physical
reads 0, read-ahead reads 0.
Is there any way to increase the performance, so that I can get the
result under 1 minute?
Any help would be appreciated.
P.S: I tried indexing the Column3, but no improvement.

Hi all
I have a table that contains an ntext column for storing values up to a couple of Mb in size.
However, I estimate that 95% of the values stored in this ntext field will fit into an nvarchar(4000) field.
Is it worth me having both fields in the table?
i.e. For rows where the values < 4000 characters I would store the value in the nvarchar column. Otherwise I would use the ntext column.
Can anyone confirm whether this technique would increase performance given that ntext values are sort of stored separately to the rest of the table data?
A colleague of mine is an Oracle DBA and he mentioned this technique is fairly caommonly adopted in the Oracle world.
Thanks
Matt

Dear Sql Server experts:First off, I am no sql server expert :)A few months ago I put a database into a production environment.Recently, It was brought to my attention that a particular query thatexecuted quite quickly in our dev environment was painfully slow inproduction. I analyzed the the plan on the production server (itlooked good), and then tried quite a few tips that I'd gleaned fromreading newsgroups. Nothing worked. Then on a whim I performed anUPDATE STATISTICS on a few of the tables that were being queried. Thequery immediately went from executing in 61 seconds to under 1 second.I checked to make sure that statistics were being "auto updated" andthey were.Why did I need to run UPDATE STATISTICS? Will I need to again?A little more background info:The database started empty, and has grown quite rapidly in the lastfew months. One particular table grows at a rate of about 300,000records per month. I get fast query times due to a few well placedindexes.A quick question:If I add an index, do statistics get automatically updated for thisnew index immediately?Thanks in advance for any help,Felix

Hi,
We are thinking about buying new harddrives to improve sql server performance. Currently TEMPDB is running on a dedicated RAID 0 with 3 harddrives of 136 GB, 10.000 RPM. When running a large bulk insert within a SSIS package to 15 destination tables we notice high numbers in the Avg. and current Read Queue length (above 3000) of the drive where TEMPB is on. No other programs or swap file is using this RAID 0 drive. Can anyone tell me if it is worth buying 4 harddrives of 15.000 RPM each 33 GB big replacing the current 3 drives? How much impact will it have on the Avg. and Current Read queue length and will it improve the time sql server needs to bulk insert data?
Thanks.

Hi,I am using SQL 2000 and has a table that contains more than 2 millionrows of data (and growing). Right now, I have encountered 2 problems:1) Sometimes, when I try to query against this table, I would get sqlcommand time out. Hence, I did more testing with Query Analyser and tofind out that the same queries would not always take about the sametime to be executed. Could anyone please tell me what would affect thespeed of the query and what is the most important thing among all thefactors? (I could think of the opened connections, server'sCPU/Memory...)2) I am not sure if 2 million rows is considered a lot or not, however,it start to take 5~10 seconds for me to finish some simple queries. Iam wondering what is the best practices to handle this amount of datawhile having a decent performance?Thank you,Charlie Chang[Charlies224@hotmail.com]

I have a SQL Server 2005 database where covering indexes had to be used to improve performance for the heavy amounts of retrievals; however, the inserts into the tables are now very slow of course. Is there any way to improve the performance of the inserts without taking away the indexes.
Would changing locking or partitioning the index help the inserts?
Other databases use a concept of "freespace" to set up in the beginning - making pre-existing space for inserts - is there anything like this in SQL Server 2005?
Thanks for any help, Mary

Basically, I have a web-based application that queries aggregates from several big tables that grow rather quickly. I feel I am fairly accomplished at tuning individual queries and have optimized these particular stored procedures as much as I can and often see great results for a period of time. However, after time passes, it seems the stored procedures begins performing really badly. What's frustrating is that I have traced the server, located a stored procedure that consistently executes with an abnormally high duration, but when I run the exact same text directly against the sql server it returns instantly.
If I recompile the stored procedure using my direct connection by including the WITH RECOMPILE clause to the EXEC statement, the problem remains for the web-app. However, if I add the WITH RECOMPILE to the actual stored procedure, it is instantly resolved. I can then remove the WITH RECOMPILE from the stored procedure text and things will remain speedy for a period of time before they again slip back.
I'm curious as to what I can do from a SQL standpoint to correct for this. For now, the app team is setting a counter for each execution and then issuing a WITH RECOMPILE when the counter limit is exceeded.
I apologize if this question has most been asked before and I have attempted a review of the forums but was unable to find any material. Any suggestions, advice, links or general assistance would be most appreciated.

Hello all,I've been recruited to assist in diagnosing and fixing a performance problemon an application we have running on SQL Server 7.The application itself is third party software, so we can't get at thesource code. It's a Client Management system, where consultants all overthecountry track their client meetings, results, action plans, etc. , and hasapparently been problematic for a long time now. I came into thisinvestigationin mid-stream, but here's the situation as I understand it:We have users reporting it's slow, with no discernable pattern with respectto what part of the application they're using or now particular time of day.I am told that it doesn't appear to be a bandwith or computer resourceproblem. They apparently added two app servers a year or so ago, whichtemporarilyimproved the performance. We're using a nominal percentage of CPU andmemory.There are three large tables (approx 8 million rows) that are queried often,as users click to see their calendar of appointments or review past meetingswith a client, etc. The activity on these tables is over 90% reads(SELECTS) with about 10% INSERTS/UPDATES. We have attempted to run the IndexAnalyzer Wizard twicebut so far it just seems to hang (it could be that the workload file is toobig?) . So, what we're doing now is isolating the SELECT statements thattake a long time to run and manually comparing them to the indexes thatexist on these large tables. Since we can't alter the SQL source code,we're trying to alter the indexes to improve performance.What I would like to know is, is there a good way to get benchmarkmeasurements so we can explicitly measure any performance changes? Also, doyou thinkwe're going about this the right way, or is there some other avenue we couldbe looking at to improve performance?I recognize that performance questions are tricky to post/answer in anewsgroup, because usually you need more information than is provided. Theproblem isthat this is a high profile investigation (they're hauling us into meetingsevery two days to report our progress) and I need to be able to convincinglystate that we have either improved performance by X% , or that it is theapplication itself that's the problem and we're stuck with it.Any thoughts would be deeply appreciated.Thanks and best regards,Steve

I have a 32-bit application which sometimes runs against 64-bit servers. When it does, I can't read the performance counters published by the FTS service because they're 64-bit only. I get event #1022 from PerfLib in the event log:
Windows cannot open the 64-bit extensible counter DLL msftesqlFD in a 32-bit environment. Contact the file vendor to obtain a 32-bit version. Alternatively if you are running a 64-bit native environment, you can open the 64-bit extensible counter DLL by using the 64-bit version of Performance Monitor. To use this tool, open the Windows folder, open the System32 folder, and then start Perfmon.exe.
Does Microsoft make available 32-bit counter libraries for 32-bit clients of the 64-bit FTS? How do I obtain those bits?

Hi everyone I am analyzing the performance on my SQL Server and need some advice on why I am seeing the results that I am.
One of my problems is that the SQL Server takes an extremely long time to execute the following command 'exec sp_spaceused' on my tempdb. This command usually displays how much free space is remaining on the selected server.
My other problem is that one of the applications that use SQL Server as a back end is acting extremely slugish. Navigating through screens, performing functions and refreshing grids take some time to execute however when I do a trace in SQL Profiler the queries seem to be executing instantly. My first thought was that the queries executed by the application needed to be optimized, but when I do a trace on the queries spawned by the application they seem fine. Does this mean that I have a network bottleneck problem or possibly a PC problem? The PC that we use to do our testing is a P4 3.0 with 512MB of ram running on Windows 2000. The SQL Server is running on Windows 2003 Server with a Raid 5 configuration 4 zeon 3.0 processors with 4 GB of ram. I feel that our desktop PC are sufficient to run any application but have received suggestions that I should upgrade my client PC's to at least 1GB of ram or move to a Citrix server, configure my SQL Server for Raid 10, try file splitting, use gigabit connections from the SQL Server to the desktops etc.
Given the facts above can someone give me advise on the most logical way to resolve my performance issue. Is my problem on the application end of things or do I need to change my network architecture and or hardware?

I have the following SQL, which works but I think it can be done simplier. I seem to have to group it by multiple columns, but I am sure there must be a way of grouping the results by a single column. Any Ideas?
Code:
SELECT count(order_items.order_id) as treenum, orders.order_id, orders.order_date,
orders.cust_order, orders.del_date, orders.confirmed, orders.del_addr
FROM orders, order_items
WHERE orders.order_id = order_items.order_id GROUP by orders.order_id, orders.order_date
, orders.cust_order, orders.del_date, orders.confirmed, orders.del_addr
ORDER BY orders.order_id DESC
