sysbench (System performance benchmark)

     是一个模块化的、跨平台、多线程基准测试工具,主要用于评估测试各种不同系统参数下的数据库负载情况。

 

  它主要包括以下几种方式的测试:
    1. cpu          *处理器
    2. threads      POSIX线程性能
    3. mutex        互斥
    4. memory       内存分配及传输速度
    5. fileio       文件IO性能
    6. oltp         数据库性能(OLTP基准测试)
  目前sysbench主要支持 MySQL,pgsql,oracle 这3种数据库。

 

安装 
    在 
http://sourceforge.net/ 查找sysbench 下载最新源码包。
CentOS release 5.4 (Final) 下 sysbench-0.4.8.tar.gz和 sysbench-0.4.10.tar.gz测试安装成功


编译安装 
    默认支持MySQL,如果需要测试Oracle/PostgreSQL,则在configure时需要加上--with-oracle或者--with-pgsql参数

./configure --prefix=/usr/local/sysbench --with-mysql-includes=/usr/local/mysql/include/mysql/ --with-mysql-libs=/usr/local/mysql/lib/mysql/

 

make && make install

 

 

说明:
--with-mysql-includes指定函数库位置
--with-mysql-libs指定头文件位置

CPU测试
sysbench采用寻找最大素数的方式来测试CPU的性能,测试例子:
sysbench --test=cpu --cpu-max-prime=20000 run

 

线程测试
线程测试私有选项:
threads options:
  --thread-yields=N      number of yields to do per request [1000]
  --thread-locks=N       number of locks per thread [8]
测试例子:sysbench --num-threads=64 --test=threads --thread-yields=100 --thread-locks=2 run

互斥测试
互斥测试私有选项:
  --mutex-num=N        total size of mutex array [4096]
  --mutex-locks=N      number of mutex locks to do per thread [50000]
  --mutex-loops=N      number of empty loops to do inside mutex lock [10000]
测试例子:sysbench --test=mutex run

 


内存测试 
内存测试私有选项:
  --memory-block-size=SIZE    size of memory block for test [1K]
  --memory-total-size=SIZE    total size of data to transfer [100G]
  --memory-scope=STRING       memory access scope {global,local} [global]
  --memory-hugetlb=[on|off]   allocate memory from HugeTLB pool [off]
  --memory-oper=STRING        type of memory operations {read, write, none} [write]
  --memory-access-mode=STRING memory access mode {seq,rnd} [seq]
测试例子:sysbench --test=memory --num-threads=16 --memory-block-size=8192 --memory-total-size=8G run

 

 

文件IO性能测试 
文件IO测试私有选项:
fileio options:
  --file-num=N                  number of files to create [128]
  --file-block-size=N           block size to use in all IO operations [16384]
  --file-total-size=SIZE        total size of files to create [2G]
  --file-test-mode=STRING       test mode {seqwr, seqrewr, seqrd, rndrd, rndwr, rndrw}
  --file-io-mode=STRING         file operations mode {sync,async,fastmmap,slowmmap} [sync]
  --file-extra-flags=STRING     additional flags to use on opening files {sync,dsync,direct} []
  --file-fsync-freq=N           do fsync() after this number of requests (0 - don't use fsync()) [100]
  --file-fsync-all=[on|off]     do fsync() after each write operation [off]
  --file-fsync-end=[on|off]     do fsync() at the end of test [on]
  --file-fsync-mode=STRING      which method to use for synchronization {fsync, fdatasync} [fsync]
  --file-merged-requests=N      merge at most this number of IO requests if possible (0 - don't merge) [0]
  --file-rw-ratio=N             reads/writes ratio for combined test [1.5]

I/O操作的支持: 
seqwr 顺序写 
seqrewr 连续改写 
seqrd 连续读 
rndrd 随机读取 
rndwr 随机写 
rndrw 结合随机读/写 
测试例子:
Usage example:

      sysbench --num-threads=16 --test=fileio --file-total-size=3G --file-test-mode=rndrw prepare
             说明:起草文件总大小为3G 16个并发线程 随机读写模式,会在当前目录下生成一堆小文件。
      sysbench --num-threads=16 --test=fileio --file-total-size=3G --file-test-mode=rndrw run
             说明:执行测试。
      sysbench --num-threads=16 --test=fileio --file-total-size=3G --file-test-mode=rndrw cleanup
             清理测试产生的所有东西。

 

MySQL测试:
查看数据库测试私有选项,每种数据库都不不一样,查看具体选项:
sysbench --test=oltp help

使用方法基本与IO测试相同,官方测试范例:
   1 、准备数据
sysbench --debug=off --test=oltp --mysql-host=192.168.1.126 --mysql-user=root --mysql-password='password' --oltp-table-size=1000000 --mysql-db=sbtest --oltp-table-name=sbtest --num-threads=20 --max-requests=10000 --oltp-auto-inc=off --mysql-engine-trx=yes prepare


2、测试
sysbench --debug=off --test=oltp --mysql-host=192.168.1.126 --mysql-user=root --mysql-password='password' --oltp-table-size=1000000 --mysql-db=sbtest --oltp-table-name=sbtest --num-threads=20 --max-requests=10000 --oltp-auto-inc=off --mysql-engine-trx=yes run

3、删除数据
sysbench --debug=off --test=oltp --mysql-host=192.168.1.126 --mysql-user=root --mysql-password='password' --oltp-table-size=1000000 --mysql-db=sbtest --oltp-table-name=sbtest --num-threads=20 --max-requests=10000 --oltp-auto-inc=off --mysql-engine-trx=yes cleanup
