服务器压力测试次数,新服务器的CPU和内存压力测试

1)工具描述

Memtester主要是捕获内存错误和一直处于很高或者很低的坏位,其测试的主要项目有随机值,异或比较,减法,乘法,除法,与或运算等等.通过给定测试内存的大小和次数,可以对系统现有的内存进行上面项目的测试.

2)下载安装

下载地址:

# cd /orahome/wangnc/os/

# rz

# tar zxvf memtester-4.0.8.tar.gz

# cd memtester-4.0.8

# make all (这样在当前的目录下会生成memtester的可执行文件)

# make install (如果需要可以通过install,把可执行文件和man文件拷到/usr/local/下)

3)简单测试

# memtester [ITERATIONS]

MEMORY是要测试的内存的大小,单位是MB;

ITERATIONS是测试次数.如果没有指定测试次数,那么测试会一直进行,直到用户终止.
