sysbench压测Oracle

安装：

yum -y install make m4  autoconf automake libtool pkgconfig libaio-devel

rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm 

之后安装bzr

yum install bzr

获取sysbench 文件

bzr branch lp:sysbench

cpu性能测试

--test=cpu                --指明要测试的是CPU 

--cpu-max-prime           --最大的素数
