I work from home, over a DSL link. Reasonably, if not hugely, fast. Everything Ent Mgr or Query Analyzer does is quite responsive, except, when I right click on a registered server. Then, there is an long wait, with no visual feedback (no hourglass) and frequently the result is nothing happens. Sometimes it takes two or even three right clicks, all spaced 15 to 20 seconds or more apart, before I get the menu. What in the heck is Enterprise Manager doing or waiting on, and why, so often, does it do nothing at all??? I realize this is a minor detail in the schema of things (sorry, couldn't resist), but it's annoying in part because it seems like it should require no outside communications and be lightning fast to just throw up a menu. I've long wondered what's happening behind the scenes on that right click......
Hi to all,I've recently installed SQL Server 2000 on Dell Power Edge 1600sc withdual processor (2.8ghz) and 1 gig of ram, to use a CRM application(Maximizer Enterprise 8.0)and since we make the install every time auser is trying to access data it take about 5 to 10 second to see therequested data. The performance of the SQL server less than thepervise version of Maximizer.I've made a typical install of SQL server 2000 and SP3.Analysis Services as been installed too.I've seen a strange memory workload this week, the used memory wasabout 740,390 kb, from my knowledge of SQL, i think this is very notnormal.Any help will be welcomeThanks in advanceV.

I have had a problem with Enterprise Manager connecting to SQL Server. At first this problem was experienced with one particular network user... whichever PC he logged onto, Enterprise Manager took ages to connect to SQL Server and every operation was painfully slow. Creating a new Windows NT logon fixed the problem.
I now have this same problem but only on my PC. It doesn't matter which Windows NT logon I use, using Enterprise Manager is painfully slow. I've tried creating a new Windows NT profile, checking the hard drive for errors, defragmenting the disk, reinstalling Enterprise Manager etc but nothing works.
What is strange is that connections from VB applications on my PC are fast. It is only Enterprise Manager that is slow.
I am using the latest service pack for SQL Server.
I thought it could be a problem with the Enterprise Manager registry values but don't want to start messing with them!
Has anyone else experienced this problem? Any advice would be great as I can't find any help from microsoft other than installing the latest service pack for SQL Server.
I am using a dial up connection to the Internet and to an online SQLServer database.I have a problem in that when I use Enterprise Manager to access evenmy local server , or even, it appears, when it is just open with noconnection to any SQL Server, I experience very slow data transferover my normal dial up connection.I am reasonably sure it is Enterprise Manager causing the problem aswhen I close it and redial I have an acceptable rate of data transferusing my dial up connection.Can anyone:a. support my conclusion that Enterprise Manager is the probablecause of the slow connection.b. suggest a solutionBest wishes, John Morgan
Hi,I am seeing very slow connections from some client enterprise managersto server. Even at server level it takes 1 minute or less to open adatabase. I have adjusted some of the memory for the SQL server, butthere are only about 60 Dbs on the server, totalling about 2 GBs.CPU is very low at all times, 1 GB of ram, p3 1.4Ghz. SQL 2k.I know I should refrag the disk, but is there anything else I can doto speed up SQL operation via enterprise manager--ODBC connections is fairly fast, as well as query analyzer.Adam
Hi,I have a table with about 70k rows. When I use open table --> returnall rows and then edit a field Enterprise Manager then says it has toreturn the entire result set for the update to take place.This can take a long time and makes editing data a slow process. Isthere any way to get Enterprise Manager just to update the one row??Thanks Tom
We are migration few database from SQL 2000 Enterprise Server to the SQL 2005 Enterprise Server (64 bit-Itanium Server)
Problem :
- The performance difference observer was not much (Just 15-18%)
- The CPU Utilization goes to 100% immediately, when the software login screen appears and it sustains in between 90% to 100%
- Multi-User Access (3 or more concurrent users), the sql performance is tremendously slow.
Steps followed for Migration:
- We have used the backup and restore method to migrate the data from SQL 2000 Enterprise Server to the SQL 2005 Enterprise Server (64 bit-Itanium Server).
- We ran the DBCC DBREINDEX for each affected tables
- We executed the sp_updatestats procedure for all the tables
- Upgraded the DB compatibility version to 90
- Installed the SQL 2005 Enterprise Server (64 bit-Itanium Server) Service pack 2.
One thing that we observed, was the memory usage, on SQL 2000 the sqlservr.exe uses around 1.5 GB where as on the SQL 2005 its just 120 MB.
A normal select query on 2000 Server took 11-12 sec, having 10 lac records, and the same query on 2005 took 1 min (3-5 sec CPU process taken by sqlservr and rest by the Sever Management Studio.
The only differance noted was that on 2000 the entire data was displayed at one go where as in 2005 the data was displayed at the 1st sec, and was filling the rest in the buffer, and to finally display entire data it took 1 min.
Also
when we run this query
select * from sys.dm_os_sys_info
one column os_priority_class shows a value = 32 ? what does this means.
In the MSSQLSERVER SERVICES, properties, there is a parameter displaying value
Advanced > Running Under 64 bit OS = No ? what does this means.
Could anyone pls suggest as to how to increase the sqlservr.exe memory area, and also how the enhance the performance.
I am writing a data access web page, but I find that the excution speed is too slow. My data base is just a data table which have five columns: id, code, quantity, price and Date. The data base has about 45000 rows. When I use OSQL or Query function, speed is just fine.
Here is the main code which I think cause the speed slow:
string conn = ConfigurationSettings.AppSettings["connectionstring"]; SqlDataAdapter adapter_2 = new SqlDataAdapter("select * from table",conn); DataSet ds = new DataSet(); adapter_2.Fill (ds,"table"); DataTable YahooOrders = ds.Tables["YahooOrders"]; DataRow[] product = new DataRow[20000];
.......
foreach (string s in split) // actually the split here has only one string in it { product = table.Select ("code like '"+s+"%' and Date >='"+minDate+"' and Date <='"+table.Select("Date = Max(Date)")[0][1].ToString()+"'"); foreach(DataRow myRow in product) { int count = Convert.ToInt32(myRow[2]); itemQuantity = count + itemQuantity; revenue = Convert.ToDouble(myRow[3]) * count + revenue;
// get product code, ignore repeated code int myIndex=code.BinarySearch( myRow[1] ); if ( myIndex < 0 ) code.Add(myRow[1]); } orderQuantity = product.Length + orderQuantity; } The first foreach actually excutes just one time, so it won' t cause any speed problem. The second foreach' s job is to sum each column of specified rows which is product here. So, any ideas about this? Thanks!
Actually from the application the developers are using count(column) to know the no. of rows resulted by a statement which joins many tables but its taking lot of time.
Is there an easy way to get the count of records(result set) of the output.
I cant use sysindexes b'z i need the count of the output genereted by the SQl Statement which joins many tables and retrieves many rows.
Got a problem (duh!). My MSSQL Server lags. Now, mind, it doesn't lag all the time. And it seems to be independent of the # of users trying to access the server. And it random clears itself up. And the problem doesn't present itself in SQL MGR, just on the web app we're running on it.
Setup: SQL Server 2k running on 2k3 w/ IIS & backup exec. All SQL data files are on a raid5 SCSI U160.
App: Intranet App developed by us for us. ASP.NET & VB.NET.
Symptoms: When queried server takes a LONG time to respond. So long infact it has become counter productive. When taking a look at the server, the CPU usage hovers between 50-75% and spikes up to 90% every now and then just for kicks. The memory usage is 2.35gb out of 4gb. To fix this we have to kill and restart all the SQL services.
Any thoughts on what to look at? There're indexes on the required FKs and the heavily queried columns. We're at a loss here.
A vendor's application is performing slow. Vendor tested it in QA and it's slow. End-users run it in PRD and it's slow. The application calls SP1, and SP1 calls SP2. Inside SP1 has a cursor. I believe as the db gets larger. The application is going to be even slower. What can I suggest to the vendor in order to fix it? Tell them to re-write the application code? Eliminate cursor?
I have 4000 record in my table employee. it takes 13 sec to get data. It this normal ? What is wrong ?

There re certian times when I want to execute a sql request (select for example) then It gets too long before I get an answer. (that happens only some times exceptionnaly). What does that mean, is it that somebody is using heavily the DB or may be using Entreprise manager or what exactly and how can I know who is responsible for taking all SQL server resources at that specefic time. What command or what tool can I use pls for this purpose. Thanks for your help.
Hello,Were using the data transfermation service to copy in an Ingres II 2.5database to an SQL Server 2000 database. Small databases don't present anissue, but when pulling one across that's about 20GB its been taking between12 and 24 hours. Both systems are relitively quick boxes and neither of themare tapped out on processor, disk I/O or network resources.I do have the "Boost SQL Server priority on Windows" checked under it'sproperties and all the processors are checked to be used.Does anyone know if there's a way to tweak SQL Server or Ingres to handlethis a little quicker? Or even an idea where the bottleneck could be may behelpful.Thanks,John.
I've got a performance question about a clr tvf that I have created. When I query the function it takes about 30 seconds for it to execute as apposed to < 6 seconds when I execute the same code in a console app (the 6 seconds includes outputting the returned data to the console, without writing the output to console it executes in about 1 second). Both the function and the app are iterating (>40,000) and returning ( >10,000) the same number of rows. I've noticed the following when viewing the executions in the PerfMon:
* the sqlclr tfv kicks the % Processor Time up to 30 for 30 seconds, the console app has % Processor Time at 9 for about 2 seconds * .NET CLR Memory - Allocated Bytes/sec spikes anywhere from 1 to 3 times during the sqlclr query at about 44MB/sec. It barely registers if at all when the console app runs. * In either case, % Time in GC is at zero.
I'm assuming that there are some configurations I'm ignorant of that can help me tune the execution. I can't imagine that it takes SqlServer that long just to iterate through the records.
I have recently decided to make the change from Microsoft access to SQL Server believing that it's a bigger faster beast with better parameterized queries and triggers and all that. BUT.I have some client data that I imported from their original paradox files.The invoice lineitem file contains over 1 milliion records.When I open this table in access and click show last record, the record is displayed in about 1 or 2 seconds.I used the upsize to SQL Server tool in Access to shift my data into SQL Server.When I use the Express Mangagement tool to open the same table and say show me the last record, it takes 17 minutes.I admit that most numeric data types have been translated to floats, so that's probably not good.But I cant alter them from floats to numeric or decimals using the table design tool.Do the conversion anomalies make up the whole reason why SQL Server seems so incredibly SLOW! ?????????
I am running the following BCP to extract a table with 156641604 rows.
bcp TestDB..data out test3.bcp -T -b1000000 -a32000
When running this i notice that the disk read bytessec counter in performance monitor on the drive that has the database devices is only reading 30mbsec. I am writing the bcp file to a different drive. Both drives are far more capable of achieving much higher IO. Is this a limitation with BCP or are there futher switches available that would speed this process up. Also the drives are both local so the bottle neck is not network. Any ideas?
Has anyone else noticed delays with SQL Express? I'm not really talking about delays on the queries but just delays in general response. For example: everything is running great, then for about 2 minutes I get connection timeouts etc can't even open stuff in the management studio without getting timeouts ... then as strangely as it started everything goes back to normal and requests are served again. The server has nothing on except 1 website, its Win 2003 Server. 512MB Ram on a PIV. The memory usage is low and during the "lockups" the machine isn't showing any processor usage and SQL mem usage is around 40Megs. I am not using User Instances either. Nothing in the event logs. What is odd, is its happening on 3 of my machines ..... all with different sites, the only thing in common between them is SQL. thanks, -c
This sounds like a pretty easy one. I have a SQL 2000 database with 2-3.4GHZ CPUs and 1GB of RAM. I have one database on it. I go in Query Analyzer on another machine and run a simple query like 'SELECT * FROM USERS' which should return 15,000 rows.
IT takes 30 (thirty) seconds to finish this query. OMG
Where do I start to decipher why on Earth this takes more than .01 seconds?
I need urgent help, about someting: i've developed and deploy an aspnet web site (data works with sqlserver), but after a few minutes working with some users, the permormance slows and stop the site.
Dear All,Finally I completed my project. Thanks all you helped me to do it.Now I have the biggest problem. In my application the Data grid is filled with Data from SQL server table which has large number of records. When I run my queries in SS Management Studio it runs very fast. To fill data to datagrid it takes lots of time. How can I reduce this time. How can I increase the performance of my Application.Thanks,Janaka
Hello, We have Sql Server installed on the Windows 2000 machine. There are 2 databases that the employees access on it. When the machine is just started, there are no problems but after some time the connections get really really slow and then eventually become impossible to connect. We did not have this problem before until we had a computer crash and then Sql server was installed on a new machine. The problems started here. We had 64mb of ram and we put in another 64mb thinking this would solve it but it did not. On the task manager the cpu percentage stays constant at 100% and the virtual memory increases and increases very slowly until it has reached it's maximum (which is 600mb). Any information would be greatly appreciated. Thanks very much, Kostas
Hi, I have a query which has suddenly started responding slow. CAn anyone tell me what could be the possibilities? I tried update stats(I am on sql 70-though it's done auto but i did it manually again) I used union all in place of union but had no big effect.any othe thought? Thanks!
Hi, Some of my queries are running too slow.It's taking as long as 30secs .Earlier the same query was taking less than 5 secs. I understand the db has grown BUT I do not know to look at this query where should i start from and what should I look into. It is on production server. the db size is 15GB and unallocated is 9GB. log space used is 4%. TIA.
I am configuring a new Server running SQL Server 7.0 sp2. I have a job that runs a large process. From the SQL Agent job, the processing time is over 8 hours. If I run the same process from a query window, it takes an hour and a half. On my 6.5 database, the job takes 2 - 3 hours from the scheduled task. What is going on with SQL Agent? I have not been able to find any information on memory and SQL Agent. Any help would be greatly appreciated! Thanks Trina Blazek
I have a dts job set up to transfer 550,000 records from a dbf file into a sql server. If I just let it run, there is a 9-10 minute delay, then it starts. If I try to schedule a job, it fails completely. I looked up ways to get it to execute quicker, mainly going to the advanced tab of the transform arrow and making the inserts 1000 at a time, the table locked, turning constraints off. Any advice on how to speed it up or why the job is failing?
I need to transfer a database from one server to another, I'm using the DTS utility because the servers have different sort orders. our database size is about 5GB which include about 2500 tables. Using DTS is taking many hours to transfer all objects and data. is there a better/faster way to do this? Any help would be appreciated, Thank you
Hi, Does any one have an idea why the backup to disk it takes 6 Hrs and to Tape it take 1 Hr.? Also what will be the diference bettewn creating the a backup device and just creating the file on the fly when I setup the backup? Thanks Felix.
I have a query that takes minutes to execute, even through there are about 300,000 records are being processed. I would appreciate any help with optimizing that query. I have two tables: User and Usage. Table user has two fields: User_Id and Date_Created and a non-clustered index on User_Id. Table usage has two fields also: User_Id and Date_Used and non-clustered index on both fields. The User table is populated when the user registers. The Usage table is populated every time the user opens a document.
Here is what I need to do: get the number of users from the Usage table who opened a document at least once after they have registered during the last 30 days for each day in the time frame, where the time frame varies. For example, if the time frame is 8/01/00 - 8/31/00, I need to get the following data:
date returns ---- ------- 8/01/00 10 (10 users returned to the document between 7/2/00 and 8/1/00) 8/02/00 15 (15 users returned between 7/3/00 and 8/02/00) . . . 8/31/00 20 (20 users returned between 8/1/00 and 8/31/00)
Here is my query:
SELECT [date], (SELECT count(distinct user_id) FROM usage u JOIN [user] ON u.[user_id] = [user].[user_id] WHERE u.[date] BETWEEN usage.[date]-30 AND usage.[date] AND u.[date]>[user].date_created GROUP BY usage.[date])returns FROM usage WHERE [date] BETWEEN @date1 AND @date2
This query works fine, but too slow. We use MS SQL server 7.0.
I am running an IIS, windows NT and Sql 7.0 My asp pages load very slow whenever the database is accessed. All the database scripts are in stored procedures. The pages load very fast when they are run on personal web server. I will really appreciate any suggestion to help fix the problem
