Linux跑分-unixbench性能测试
我们在选择和评论一款VPS的性能时候，从理论上我们会从配置信息、硬件对比，以及带宽速度，包括这里老蒋要分享的UnixBench跑分测试。尤其是跑分测试数据基本上可以反映出这款VPS的整体性能数据，但是也不能作为唯一参考。比如之前我在Linode VPS上面测试的跑分数据在500-700之间，但是有些OPENVZ VPS跑分在2000-3000，UnixBench跑分仅仅是作为参考，一般在400分以上都差不多。
// 安装运行环境
yum install -y make gcc g++
// 下载
wget https://github.com/aliyun/byte-unixbench/releases/download/v5.1.6/UnixBench-5.1.6.tar.gz
// 解压
tar -zxvf UnixBench-5.1.6.tar.gz
// 运行，从releases下载的是已经编译好了的
cd /UnixBench-5.1.6/UnixBench
./Run

# 测试聚焦在字符串处理，没有浮点运算操作。这个测试用于测试链接器编译、代码优化、内存缓存、等待状态、整数数据类型等，硬件和软件设计都会非常大的影响测试结果。
