I have been using sysbench for a while on a Pentium 4 running FreeBSD 6.2 and it’s been a great tool providing great performance information when it comes to upgrading hardware components. I noticed that hardware components may have a substantial impact on MySQL’s performance, especially when you choose between genuine and so called “no-name” components.

Jon,

You should contact author of sysbench

Does anyone know where I can find a copy of the Windows port of Sysbench? This would be extremely helpful for testing.

Hello Mihir,
It is exciting to hear that sysbench can now be run on Windows and even has a driver for SQL Server. Please let me know if you are interested in including this patches into the upstream version.

Regarding the duplicate key error, since this is not directly related to this blog, feel free to contact me directly at kaamos@users.sourceforge.net or in the mailing list sysbench-general@lists.sourceforge.net. Please also provide the exact command line used to start sysbench.

Best regards,
Alexey.

Hi,
I have ported sysBench for windows environment and seems to work just fine with SQL Server 2005. But on certain occasions i receive follwong primary key violation messages…

ALERT: failed to execute SQL query: `INSERT INTO sbtest values(5694934,0,’ ‘,’aaaaaaaaaaffffffffffrrrrrrrrrreeeeeeeeeeyyyyyyyyyy’)`:
FATAL: 23000 [A43] [Microsoft][ODBC SQL Server Driver][SQL Server]Violation of PRIMARY KEY constraint ‘PK__sbtest__7C8480AE’. Cannot insert duplicate key in object ‘dbo.sbtest’.

First i thought my db is corrupt so i build a new db. I still get these errors. Can anybody provide any help?
Thanks,
Mihir

Looks like we cannot use max_requests and max_time simultaneously?? Am i right???

Mihir,

You determinate number of threads and max number of requests depending on benchmarking needs. First is concurrency second is a way to restrict length of the rest.

CPU usage should be high on CPU bound workload if Server scales well.

How do we interpret sysbench results?? I was able to port sysbench for windows and am running on a MP platform (4Sockets/8Cores/16Threads).
I am running with following command.

sysbench.exe –test=oltp –oltp-table-size=1000000 –num-threads=32 –max-requests=100000 run

How should I determine number of threads, max requests??

Also, It is possible to drive CPU utlization higher (close to 100%)?
Please help!

Thanks
