SysBench – benchmark tool

Posted by Vadim |

Sysbench is benchmark developed by Alexey Kopytov (software engineer @ MySQL AB)
- http://sysbench.sourceforge.net/ and I want to write a short intro about this tool as sysbench is one of software for my everyday use. For example, SUN published their Solaris vs RedHat stuff based on sysbench’s results (Peter and me provided performance consutling for this publishing).
Sysbench has a lot of options and details so my goal is describe common usage of benchmark.
Sysbench allows to test:

  • file I/O performance
  • scheduler performance
  • memory allocation and transfer speed
  • POSIX threads implementation performance
  • database server performance

First four is useful for the platform evalution, for example if you want to compare speed of file I/O and implementation of threads on different servers – I will write about in further notes. Regarding database benchmarks – in 0.4.7 and earlier versions Sysbench supported only predefined set of queries, but that will change in version 0.5 where sysbench is scriptable (Lua http://www.lua.org/ as scripting language) , and you can use your own tables and queries. 0.5 should be realesed soon. Originally Sysbench supported only MySQL, but later Oracle and PostgreSQL (and deviations, e.g EnterpriseDB) were added – it is not clear from Docs page, but it is :) . Sysbench uses only a native API, not middle layers like ODBC, that is why list of supported DB is not wide. Other restriction Sysbench can’t be complided on Windows – well you can try and write about your experience. In next notes I’ll write how to setup and perform database benchmarks.

    How would i go about using sysbench on Windows Server 2003 and SQL Server 2005? Can you provide with sysbench.exe for windows????

    Thanks

    I’m afraid it is not supported on Windows.

    I heard someone has done the porting to Windows but it would not support SQL Server without addition work anyway.

    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

    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.

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

    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

    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.

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

    Jon,

    You should contact author of sysbench
    at kaamos@users.sourceforge.net

    There was a port to windows but I do not know current status of

    Hi,

    When i use –max-request option there is no deadlock. If i take that of from the sysbench run script, then there occurs deadlock error? what is the hidden info. and i was very new to sysbench

    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.

    Hi Mihir,
    We are keen in running sysbench on windows. Can you help us on that
