sysbench是一款测试工具

主要包括以下几种方式的测试：

     1、cpu性能

     2、磁盘io性能

    3、调度程式性能

     4、内存分配及传输速度

     5、POSIX线程性能

     6、数据库性能(OLTP基准测试)现在sysbench主要支持 MySQL,pgsql,oracle 这3种数据库

安装

Debian/Ubuntu安装：

sudo apt-get install sysbench

CentOS/Fedora安装:

sudo yum install sysbench

如果提示“No match for argument: sysbench”，先执行：

yum -y install epel-release

然后在执行安装即可。

测试例子：

sysbench cpu --cpu-max-prime=20000 --threads=2 run

返回结果：

sysbench 1.0.20 (using system LuaJIT 2.1.0-beta3)

Running the test with following options:
Number of threads: 2
Initializing random number generator from current time


Prime numbers limit: 20000

Initializing worker threads...
