COLOR=Blue]Hi all,
What can be the reason there is a high CPU usage even when there's only 1 database being accessed. As a result the database is really really slow.
CPUperformance usage goes as high as 100% and I can't for the life of me figure out what's causing it. The indexes are being rebuilt 3/4 times a week and I've checked to make sure there aren't any locks or anything.
Any other ideas? [/COLOR]
Thanks

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.
hi all
I got a small MSSQL server.. total database file size less than 7GB. with 2G rams installed 2 cpus. but for some reason when i check the task manager process mem usage is over 1.7G. the sql server memory setting in on Dynamically not fixed. and maximum 2G i believe is default. anyway. my question is over 1.7 memory usage is too high? because i dont have alot of transaction going. and cpu usage is very low. wondering if this's normal or not. and if is not normal . what cause the memory usage so high...... and how can i adjust back to normal. ? can anyone help me out? or any suggestion? thanks
Hi
I have an sql server with very high usage. The web which is connected to the sql server has approx. 1000 unique visitors every time.
The database is optimized and the site goes really fast now.
But a problem we've had since the beginning is that SQL Server constantly uses 1.8 GB of RAM. Never less, never more.
Do you have any idea on how to decrease the usage of RAM. I am sure that this high usage is necessary.
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!
Hi all,
I have a problem with sqlservr.exe (version 2005). It use alot of memory. I check on taskbar manager sqlservr.exe usage (CPU 10 - 20%, Mem usage - 1,493,688/2GB Ram). I dont know how can I fix it. Some body could help me please.

Anyone aware of anything I can look at to improve performance of my SSIS packages? i basically have two master packages that call about 15 child package tasks each. All the package tasks are called sequentially and all they do is just load flat files into temporary tables and execute a simple stored proc. Each package tasks check to see if a file is there and if so it processes it else it just ends. The packages are scheduled to run every minute to check for files. If I watch the CPU during execution i can see the two instances of DTSEXEC.exe running and consuming about 25-30% of the CPU. The box that this runs on is a Quad processor with 4 GB of ram.
Any ideas on how to improve the performance of this? I have tried playing with the transaction level, but that didn't seem to do much performance wise.
Thanks for the help!
Just built a new DB server. Using SQL2K5Standard 64bit on W2K3Server 64bit. Hardware includes 16GBs memory/dual 4-core procs and many spindles, however we only have a 2GB page file on C:. SQL is set to to usa a maximum of 12GB memory which is way more than it should need. Problem is, we are occasionally seeing very high page file usage. If Task Manager is correct, (which it really can't) I am using 10 and 13.8GB (as listed in PF Usage) But I only have a 2GB page file! Occasionally when simply copying a file from one partition to another, PerfMon shows Pages/sec jump to 10,000. Also see some very high Disk Queueing.This system isn't even in production yet. My main questions are two: 1) some documentation says with SQL2K5-64 bit running on W2K3-64bit I may not even need a page file. Is this correct? 2) What would be causing high usage of the swap file with 16GBs of installed memory? And help would be appreciated. Thanks in advance!

I am trying to find out what could be causing this issue. Why would we be waiting on cpu when its barely being used. Signal waits are varying from 35 to 55% and cpu usage is only at 5% usage.We are using Windows Server 2012 with SQl Server 2012 Standard edition with cpu5. There are 3 instances on the server each with max memory 50gb memory and the server has a total of 190gb memory. The machine is a 12 core machine with hyperthreading enabled.
View 8 Replies View RelatedI have six stored procedures that I have to run hourly during the day. When I schedule them into separate SQL jobs (they must run concurrently), the percent CPU of Sqlagent90.exe process goes way up, eventually pegging out the overal CPU usage on the server. When I run the six stored procedures concurrently from query windows in SQL Server Management Sudio, the overall CPU usage stays very low.
Is there something about the SQL Server Agent that inherently adds CPU overheard? Thanks in advance ....
I have been having issues with our SQL server for awhile now. It seems to run out of memory every few days and when I look at the memory dump, the MEMORYCLERK_SQLOPTIMIZER seem to take over memory and eventually cause the server to crash.
Here is the SQL verison we are using: Microsoft SQL Server 2012 (SP1) - 11.0.3460.0 (X64) Jul 22 2014 15:22:00 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.2 (Build 9200: ) (Hypervisor)..It is on a VM on Windows 2012 server. It has 20gb of RAM allocated to it and the MAX Server Memory is set to 16.5gb.
I have seen the MEMORYCLERK_SQLOPTIMIZER grow to about 11gb at the time of the server crash. Why that is happening? What is causing the memoryclerk_sqloptimizer to get so high? I have looked it up and it looks like it has to do with ad hoc requests, but is there something I can do to bring that memory down when it gets so high so that I can prevent a server crash?Do we just need to add more memory or is there a memory leak somewhere?
I know I should probably be posting this in the RS section but I have a Win 2008 R2 server and RS 2012 along with SSIS and Database server installed. I also have SQL 2005 instance with Sql 2005 SSIS running on the server.
I saw that Reporting services was consuming 9gb of ram a few days ago with no published reports. It's just a default install.
So I investigated the settings and the document: [URL]......
I added this section to the reportserver.config file to restrict memory usage
<WorkingSetMaximum>512000</WorkingSetMaximum>
<WorkingSetMinimum>128000</WorkingSetMinimum>
Any example altering the reportserver.config file in your standard build of sql server reporting services?
Hello sql and .net gurus :-)I have a problem with my website www.eventguide.it. It's completly developed under .NET 2 and SQL Server 2005 Express. My problem is the folowing:The server is a Intel 3Ghz HT processor with 1GB Ram. No other page on the running system is a CPU consuming site. We optimized the SQL statements, the code, the caching and many other parts of the website (pooling on SQL access), but the SQL Server uses about 50% to100% of the CPU and about 400MB RAM all the time. The whole site seems to be very, very slow. In fact there are many of SQL operations on every page request, but we cache a lot of them in different ways (page output caching, application caching). So I don't understand we have so much performance problems. Any suggestions for optimised code in general? I read nearly all of the MS .NET performance papers - but real world experience is the missing part :-) It is better to cast the values of a SQL reader like thisDim String1 as String = Ctype(DataReader.item(0), String)Dim Integer1 as Intger = Ctype(DataReader.item(1), Integer)or like thisDim String1 as String = DataReader.item(0)
Dim Integer1 as Intger = DataReader.item(1)Thanks a lot for your help!FOX
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 have a client program that writes to sql server database 10 records per second . i want to compute the CPU usage and the memory usage for the whole program or CPU usage,memory usage for the insert statement in the program .
Can anybody help me with this?
Hello, When I am seeing SQL Server 2005 Management studio Server Dashboard> I am seeing my(USERS) databases and msdb database usage is very small % of in CPU Usage(%), Logical IO Performed (%) Usage pie chart.
90% of Total cpu usage is showing for Adhoc Queries. what excatly this means in Dashboard? if application uses more than it would have shown in Database level or not?
sicerely this dashboard is good, if any one is watching daily, please advice their experiences here.
Thanks in advance. Hail SQL Server!
providing a query for fetching the data for CPU Usage, Memory usage, blocking and all details ...
I want to create a job which will run on a Node every 15 min and store data in a table for each instance...
DMV is not giving more stuff and xtended events not sure if i can store that data into a table?
I need to use a system-generated key and will have over 2 billion items.
I'm considering using a data type like the following.
Decimal(19,0) will give me the large numbers I need without making my index wider than 9 bytes.
Uniqueidentifier is 16 bytes.
Anyone know if this will cause me pain in the future? Specifically using @@identity after inserts to get the value (i tested it seems OK).
CREATETABLEIdentityTest
(
MyIDDECIMAL (19,0)IDENTITY (1,1),
MyCharchar(1) NOT NULL DEFAULT 'Y'
)
Any ideas welcome.

After a fresh install of SQL 6.5 with SP5a(or without), the cpu is running at anywhere from 50%-80%. It is loaded on a PDC, but when I stop the sql service cpu utilization drops to 0-2%. When I start the sql service it's right back up there, does anyone have a suggestion as to how to fix this or why the service would be doing this?
Thanks, Christel
Hello everybody,
We are starting new project
Customer validation with minimum wait time.
How to insure High-Availability?

Hello,
We are experiencing high disk i/o on one of our RAID disk systems. Can someone tell me how I can identify the query or user or process which is causing this high disk i/o?
Thanks,
Brent.
I am getting high CPU utilization on the SQL Server process (>90%).
However the overall utilization (NT -- entire box) always seems to be under 50%.
Can someone explain why this is happening. The server is a quad; the SQL server process seems to be using only two CPUs at a time (not the same ones all the time).
Lightweitht pooling has been turned on and the maximum worker thread size has been left at the default value (255).
How can I configure SQL options to spread the load across all four CPUs ??????
I have a summary table with a 9 field composite primary key. Every 10 minutes, my system generates 2 files of 500,000 to 750,000 rows to be summarized into this table. I first Bulk insert those into a temp table, and then trigger an inner-join update query to do the updates, followed by a left-outer join to do the inserts. As the day goes on, millions of rows in my summary table, this process is too slow. Any ideas about causes/solutions???

View 1 Replies View RelatedCould anyone help me in finding out why the cpu utilization is very high??
I have two servers say, Server A , server B. There is a transactional replication going on from server A to B
There is a table say Table A on server A, which is being replicated to server B.
I created a trigger insert and update trigger on Table A on server B (i.e. on subscriber). Since then, the CPU utilization for server B is very high 80-90%
when i used profiler, i could see .whenever replication stored proc for insert or update executes..cpu utilization goes up..
trigger just insert the updated/inserted rows into some other table.
Could anyone tell me why the cpu utilization has gone up so much?? i am using sql server 2005
thanx

Hello,
Throughout the day our Document Management application generates high busts of physical page reads when users query the database.
What SQL configuration parameter(s) should I check/modify to insure that the database is performing at it's optimun during these bursts?
Thank You in advance.
I have a few in house developed application (VB based) that access the SQL server for adding, appending , creating tables. The application does the changes thru queries dynamically generated at the application level.
My MS SQL Server runs on a PIII / 256 MB Ram / 18 GB HDD
The problem is that the memory utilization of SQL server keeps growing constantly. Out of 512 MB (256 Physical + 256 Virtual) available teh memory utilization reaches a level of 490 MB and statys constant. Though SQL Server shows a utilization of 150 MB.
I suspect that SQL is not releasing memory back to the system. Please help in resolving. The problem may lie at the applications developed.
