Problem With Server Slowing Down Because Of High Amounts Of Users On At The Same Time!
Jan 24, 2008
The server being used is a Intel Xeon E5310 Clovertown 1.6GHz 2 x 4MB L2 Cache Socket 771 80W Quad-Core 2U Passive Processor.
The problem is that this server is slowing down everytime about 1000 users log into a forum which the server is running. I think that the server should be able to handle this many users with no problems but I am not sure if that is the case.. The problem is probably something to do with the SQL of the server I am guessing. The server is not mine but I want to help the owner of the server as well as the users who are trying to access this forum but cant because of this server issue. If I was able to get the SQL would I be able to fix this problem? I doubt you need this but the server url is www.smashboards.com
I am fairly new to servers and have never really set one up myself yet. Forgive me for my lack of knowledge about them.
-Thank you!

Hi,We need to use a free database for a project because of tight budget.Is MSDE ok for handling large volume of data and 70 - 80 users?My understanding is that MSDE is optimized for 5 concurrent users.Is MySQL better than MSDE?Thanks,Ben

I'm running into an issue when developing a clr project. I open the project to make changes and apparently it hoses up the sql server that I'm connecting to. I'm opening the CLR Project from a mapped drive on another computer. I can't figure out why just opening up the project causes the slow down. Any ideas.
Thanks,
Josh

We have a process here where a ~45Gb is copied from DB1 to DB2 (both on the same server) using the Export Data wizard and choosing the "Transfer objects and data between SQL Server 7.0 databases" - All the defaults are left as is.
Under 6.5 this method took around 24 - 26 hours, now with SQL 7.0 (SP3) it takes about 16 hours. That's great execpt towards the end of the copy it seems to be hogging most of the server resources - although the processors aren't mazed out.
Users of the other databases are having queries take 5+ mins when they normally come back in < 5 seconds. As soon as the copy finishes there query time return to 'normal'.
Anyone any ideas on where to start looking or how to analyse this problem.
Thanks in advance.

We're having problems with our SQL 2000 SP3 standard server (on Win 2k3). Our quasi-data-warehouse application does data processing on feeds of approximately 7 million records. Once the data is loaded in the queries against that data and updates against large tables will often wait with PAGEIOLATCH_SH contention. To give an example, over 7 million rows I was testing something out in development and issued: UPDATE <Table> SET <VarcharColumn> = null, which took forever (over an hour) with the PAGEIOLATCH problem....meanwhile someone else using another database was completely blocked from making an update during that time. It seems like something is very wrong.
The server has 4 drives spinning at 15k rpm with some sort of a high end raid controller, so I'm sure it's not a slow i/o subsystem.
Has anyone experienced this behavior before? Is this an issue that's resolved in 2000 SP4?
Thanks in advance,
-Mark

Hello there,
I have a SQL Server 2000 with a dozen of databases. The databases are rather small (all sum up to 10 GB).
The entire server gets extremelly slow from time to time (lasting a few days when it happens and suddently coming back to normality). A profiler trace doesn't show anything strange (besides a lot of SQL Agent entries).
I pretty much tried to isolate every single application that makes use of the databases in that server and see if it was the cause of the problem, but I couldn't find any correlation.
I know the computer where this server runs is quite fragmented. Is there any way I could make sure this is the cause of my performance issues?
I don't know if this might help, but once the server simply went down for some 3 hours, and I wasn't able to bring it up in any way. It eventually started working again by itself. The only thing I did in the meantime was to run DBCC CHECKDB a few times, always getting the response "No errors found on the database".
Any hint on that?

Hi everybody,
I have a query slower in SQL Server 2005 than in SQL Server 2000. I have a database in SQL 2000, I put it on the same server, but with SQL 2005 and the query take 5 seconds instead of 0 seconds. The DB compatibility is SQL Server 2000 (I tried with 2005 and result is the same). Execution plan seems right and I tried to change some DB options without results. It is weird, when I remove left join on MandatsEx, it take 2 seconds. The view currentEmployeeLevelHistoric returns 45 000 rows and mandatsex has 0 rows.
Here is the sample:
Select ls.EmployeNiveau.pk_EmployeNiveauID as NoNiveau,
IsNull(nullif(ls.Traduction.Description, ''), ls.TraductionDefaut.Description) + ' (' +
ls.currentLevelHIstoric.NoNiveau + ')' As Nom,

ls.EmployeNiveau.assignmentReason As AssignmentReason,
ls.currentEmployeeLevelHistoric.FinAssign As DateAssignationFin,
ls.MandatsEx.noDossier, ls.MandatsEx.pk_MandatID,
'' As Period, ls.currentEmployeeLevelHistoric.NiveauPrincipal,
ls.currentEmployeeLevelHistoric.pk_emplNiveauHisto_Id,
ls.EmployeNiveau.fk_NiveauID_Niveaux, ls.EmployeNiveau.No_Ent_leg,
IsNull(nullif(TradPere.Description, ''), TradDefautPere.Description) + ' (' + NiveauPere.NoNiveau
+ ')' As NomSup,
ls.EmployeNiveau.No_Ent_leg + ls.EmployeNiveau.no_divisio + ls.EmployeNiveau.no_sec_eco +
ls.EmployeNiveau.no_etabli + ls.EmployeNiveau.no_mat as employeeScope,
case when ls.mandatExternalisation.fk_mandatID_MandatsEx is null then 2 else 1 end as

Inner Join ls.EmployeNiveau on
ls.currentEmployeeLevelHistoric.pk_EmployeNiveauID = ls.EmployeNiveau.pk_EmployeNiveauID

I am currently investigating aa high avg write time ms issue (145ms) which seems to be only occuring on the tempdb data files.I have followed the recommended setup of TEMPDB in that
1. Data files = number of physical cores
2. Data files and logfiles are on separate partitions away from the other databases.
3. Tempdb is presized and no incremental file increases look like they are happening with frequency.
We have sharepoint 2012 setup on other sql servers and with TEMPDB setup following the same guidelines, with far more Sharepoint activity on a similary specified hardware which is why its confusing.FileIO auditing on the partitions themselves shows that the FileIO is very fast on the partitions that the tempdb data file which leads me to beleive that Sharepoint may be the culprit perhaps due to excess use of tempdb with operations taking a long time to resolve.

I am trying to understand an environment and provide a solution to Banking system so that they can enter user data (transactions) online and at the same time we can provide users online reporting as well. Using same sql server or server/hardware on other machine.
There are so many branches/customers/ATM machines accessing online data as well as updating their balances. I want to understand how can we provide online reporting. Through replication, transaction log backup, log shipping or what other solution is available. I need to understand this and provide a solution that is already implemented running/successfully. Need some proposals and their pros and cons. cost and maintenance are the constraints with the real time reporting on live system/database.

We recently implemented merge replication.We were expereincing. The replication is between 2 SQL Servers (2005) over same network box, and since we have introduced the replication, the performance has degraded considerably on subscriber end.
1) One thing that should be mention is that its a "unidirectional Direction" flow of changes is from publisher towards subscriber (only one publisher and distributor as well and one subscriber ).
2) Updates are high than inserts and only one article let say "Article1" ave update up to 2000 per day and i am experiecing that dbo.MSmerge_upd_sp_Article1_GUID taking more cpu time.what should be do..
on subscriber database response time is going to slow and i am experiencing a lot of number of LOCK time outs on application end.
can any one can also suggest me server level settings for aviding locking time out.
looking for any experieced solution/suggestion.
Thanks in advance.

Hi,
Is there a way to configure mirroring to go from High Availability to High Protection without having to reconfigure Database Mirroring? Using the interface in Management Studio, I can change the configuration option to High Performance, but not High Protection despite both of them being Synchronous.
If not, what are the recommended steps to configure the mirror once it already has been configured? Is just like initially setting up the mirror or would there be any shortcuts I could take? If I stop the mirroring and remove the witness, will the High Protection option be available?
Thanks,
J.

Hi There
I realise this is a stupid quesiton but i cannot really find any confirmation of this in BOL.
If you are running High Safety with automatic failover, when failover occurs does this automatically change to High Performance mode. SInce for failover to occur something has happen with the primary , it will be impossible to commit transactions on the new primary and mirror asyncronously since 1 of them is no longer available.
So am i correct in assuming that automatic failover also automatically changes the mode to High Performacne for that session?
Thanx

I'm in the process of migrating a lot of data (millions of rows, 4GB+of data) from an older SQL Server 7.0 database to a new SQL Server2000 machine.Time is not of the essence; my main concern during the migration isthat when I copy in the new data, the new database isn't paralyzed bythe amount of bulk copying being one. For this reason, I'm splittingthe data into one-month chunks (the data's all timestamped and goesback about 3 years), exporting as CSV, compressing the files, and thenimporting them on the target server. The reason I'm using CSV isbecause we may want to also copy this data to other non-SQL Serversystems later, and CSV is pretty universal. I'm also copying in thisformat because the target server is remotely hosted and is notaccessible by any method except FTP and Remote Desktop -- nodatabase-to-database copying allowed for security reasons.My questions:1) Given all of this, what would be the least intrusive way to copyover all this data? The target server has to remain running and berelatively uninterrupted. One of the issues that goes hand-in-handwith this is indexes: should I copy over all the data first and thencreate indexes, or allow SQL Server to rebuild indexes as I go?2) Another option is to make a SQL Server backup of the database fromthe old server, upload it, mount it, and then copy over the data. I'mworried that this would slow operations down to a crawl, though, whichis why I'm taking the piecemeal approach.Comments, suggestions, raw fish?

Hi there - I have a longish bit of MDX which enable some MTD reporting. I'd like to power up the report so that users can select to report by WTD, QTD, YTD by clicking hyperlinks / buttons / whatever [I'm quite new to reporting services - not quite sure what's possible.]
I could create 4 separate reports with 4 separate datasets, or one report with 4 datasets, or is there some reasonable way I can tweak the MDX for a dataset on the fly, e.g. "search and replace, find MTD replace with QTD" &c &c.
Cheers,

HiI have a VB.net web page which generates a datatable of values (3 columns and on average about 1000-3000 rows).What is the best way to get this data table into an SQL Server? I can create a table on SQL Server no problem but I've found simply looping through the datatable and doing 1000-3000 insert statements is slow (a few seconds). I'd like to make this as streamlined as possible so was wondering is there is a native way to insert all records in a batch via ADO.net or something.Any ideas?ThanksEd

Hello,Currently we have a database, and it is our desire for it to be ableto store millions of records. The data in the table can be divided upby client, and it stores nothing but about 7 integers.| table || id | clientId | int1 | int2 | int 3 | ... |Right now, our benchmarks indicate a drastic increase in performanceif we divide the data into different tables. For example,table_clientA, table_clientB, table_clientC, despite the fact thetables contain the exact same columns. This however does not seem veryclean or elegant to me, and rather illogical since a database existsas a single file on the harddrive.| table_clientA || id | clientId | int1 | int2 | int 3 | ...| table_clientB || id | clientId | int1 | int2 | int 3 | ...| table_clientC || id | clientId | int1 | int2 | int 3 | ...Is there anyway to duplicate this increase in database performancegained by splitting the table, perhaps by using a certain type ofindex?Thanks,Jeff BrubakerSoftware Developer

Hi,
When we generate a report with an account that is in the admin group it takes 2-3 seconds but when we do it with another user it takes over 2 minutes... any reason for this?
(The "Report is being generated" thing, by the way)
Not sure if my question is clear, I've been looking and searching for the past 2 hours but can't find anything remotly close to that problem... any help would be appreaciated!

I am working on a stock price analysis project. Stock prices are stored in SQL Server as tick by tick data (that means in a high frequency) and need to be grouped by minutes in order to display them as as high, low, open and close prices in a candlestick or similar chart.
The fields in the table are:
Time (for every stock price tick)
Price (stock price)
Symbol (of the stock)
A sample time series would look like this:
11:45:01 $22.11 MSFT
11:45:02 $22.10 MSFT
11:45:04 $22.25 MSFT
...
...
...
11:45:58 $22.45 MSFT
11:46:03 $22.22 MSFT
11:46:08 $22.25 MSFT
...
...
...
11:46:59 $22.45 MSFT
The result of the SQL query should be:
Symbol Time Open High Low Close
MSFT 11:45 $22.11 $22.45 $22.10 $22.45
MSFT 11:46 $22.22 $22.45 $22.22 $22.45
This is the SQL statement I came up with but obviously doesn't work:
SELECT DATEPART(Minute,Time), MIN(Price), MAX(Price) FROM dbo.TimeSales WHERE Symbol='MSFT' GROUP BY DATEPART(Minute,Time)
I would appreciate any suggestions.
Thank you!

Hi all,
I want to raise one question which might not relevant to current discussion.
Prob:-- I have some SSRS reports. I want to know for a given time period
1. How many people hit the report.
2. Who are the users hit the report in that time interval.
Is there any query to get that data?
Or,
should I go somewhere to see the data?
NB:- There is not any table in the application which is storing the data

I've been doing some experiments with speeding up copying tables ofapproximately 1 million rows between databases using BCP and BULK INSERT.I noticed that the total time for removing the indexes (non-clustered) andthen recreating them after the BULK INSERT was significantly less than justdoing the BULK INSERT with the indexes left there, even though I specifiedTABLOCK.I would have expected SQL Server not to update the index until the insertcompleted (given the table lock) and so removing the indexes would have noeffect. Can anyone explain why removing the indexes should speed it up?This is on SQL Server 7.CheersDave

Hello:
Interestingly enough, I haven't come across this before. I have a SQL stored procedure which takes four parameters; periodstartdate (datetime), periodenddate (end time), hsgradyearstart (int), hsgradyearend (int)
[dbo].[CalculateActivityTotal]
-- Add the parameters for the stored procedure here
@periodstartdate datetime = '2007-01-01',
@periodenddate datetime = '2007-01-08',
@hsgradyearstart int = 1900,
@hsgradyearend int = 2007
AS...
If I run the stored procedure and pass the parameters using EXEC or
sp_executesql "CalculateActivityTotal '2008-01-04 12:00:00', '2008-01-11 12:00:00', 1900, 2008"
the stored proc takes well over ten minutes to run (it does a bunch of aggregation). If I modify the stored procedure to take no parameters, however, and I hardcode the dates in the stored proc using declare and set then it runs in 13 seconds. What could be causing my problem and how I can I go about resolving this? I need to pass the parameters via reporting server. Thanks!

Hi,
For the last week, our production SQL server is running very slow and causing the CPU usage to go 80-100 % almost all the time. This causes certain queries to time out. Our application has never timed out before ever. Also, we did not do any updates on our production machine or installed anything recently.
Has anyone of you ever experienced this issue? If yes, then what did you do to resolve it? any help would be greatly appreciated.
Thanks for your help!

We have a live server that has had very high CPU usage in the last few days, therefore the site is extremely slow. There are about 60,000 users per day on the average. It always had high CPU usage, but not as bad as in the last few days, in the 90s, sometimes even reaching a 100.
Any solutions? I've run SQl Profiler to check on queries that have high CPU usage. When I run the same queries on our staging server, they are very quick. For example, the same query can take 1 minute on stage, but 12 minutes on the live site. We do know that this is also related to traffic, during lower traffic times, the same query takes less time, but still never as fast as stage.
Oh yeah, it's SQL Server 2005 and asp code running IIS6 on windows 2003 server.
Please help. I really appreciate any advice. Thank you.

I've been asked to look into the possibility of using SQL Server in a high availability environment. We have a few web based applications that use SQL Server back end DBs. What we are looking into is whether we can use multiple instances (on multiple physical servers) of SQL Server using some type of clustering/load balancing. I haven't worked with SQL Replication before, so I'm not even sure where to start in exploring the possible avenues we can explore.
Can anyone push me in the right direction? Any info would be greatly appreciated!
Thanks,

To All,I have a SQL2KSP3a database(<1GB) running on a 4x3GB physical CPU with4GB of ram. It is Windows Server 2003 with hyper-threading turn on.There are ~420 .Net users/cxns (fat client, no web/app servers) withconnection pooling and ~1 trx/sec. The database growth is neglegeableand actually is not even relevent which I will explain in a minute.99% of the trxs are from one SP that does a select. The resultsets arerelatively small as well 1~100 rows. Yes I have tuned it with indextuning wizard as well, changed the SQL memory configurations, etc....My problem is this...The first day after a reboot, the server runs 6%CPU during peak hours.During the non-peak hours until the next day something apparentlyhappens. The next day (2nd day after a reboot), it jumps to 40%CPUduring peak hours. The server will continue to run at 40%CPU duringpeak hours until the next reboot. This phenomenon has been occurringfor 6 months or more and the traffic on the server is the same for day1 as it is for day 2,3,4,... This database was on another server with100+ dbs and exibited the same behavior, thus bringing that server toits knees, and thus we had to move it to the server in question with noother dbs.I have googled my eyes out, Microsoft site, white papers, perfmon,SQLDiag, PSSDiag, execution plans, index tuning wizard, and the listgoes on! I currently have a case open with Microsoft that has beenopen for months now. I have been passed around to the 3rd "MS TechSpecialist". I have ran PSSDiag a total of 6 times for them for hourson end. I have changed MAXDOP. I could give more information, but Iwould be here for days. I am running out of patience/ideas andMicrosoft is apparently blowing smoke.Any ideas are greatly appreciated!Thanks in advance!JL

Hi,We have a prod server running on SQL server 2000 64 bit. It is a4cpu server with 16GB of RAM. we have a maxmemory setting of 15.5GBfor sql server. Inspite of 15GB being available for sql server, itstill uses paging file space, a lot. When looking thru task maanger wecan see sql server using 15.5GB of Memory usage and 22GB of Virtualmemory usage. I don't understand why it should even be using closer to7GB of Paging space, when it has so much memory. How does SQl serveruse Virtual memeory vs Physical memory?HAs anyone seen this before.ThanksGG
