摘自 Linux内存压力测试-memtester工具，如有侵犯，请告知删除
最近要测试一台机器的整体性能情况，就在google搜索一番，发现这个一个小工具，说是可以进行内存的压力测试，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。
1 下载
wget http://pyropus.ca/software/memtester/old-versions/memtester-4.2.2.tar.gz2 安装
tar zxvf memtester-4.2.2.tar.gz cd memtester-4.2.2 make && make install3 参数介绍
memtester [-p PHYSADDR] <MEMORY> [ITERATIONS]- MEMORY 申请测试内存的数量，单位默认是megabytes(兆)，也可以是B K M G- ITERATIONS 测试的次数，默认是无限4 测试样例
开始测试，申请10M内存，测试一次，如下图：
5 适用心得
主要想对内存进行压力测试，以上只是试用，可以申请大内存，放入后台无限测试
nohup memtester 2G > /tmp/memtest.log &Note:
进行跨平台交叉编译时，请修改文件 conf-cc 及 conf-ld
conf-cc (修改编译器, -static 可选)
cc -O2 -DPOSIX -D_POSIX_C_SOURCE=200809L -D_FILE_OFFSET_BITS=64 -DTEST_NARROW_WRITES -c=> arm-linux-xxx-gcc -static -O2 -DPOSIX -D_POSIX_C_SOURCE=200809L -D_FILE_OFFSET_BITS=64 -DTEST_NARROW_WRITES -cconf-ld (修改编译器)
cc -s=> arm-linux-xxx-gcc -s自己战胜自己是最可贵的胜利。
