前几天用简单的命令测试了GS的性能，那时只测试了下载速度、磁盘性能等，今天抽空给MediaTemple GS做了个UnixBench跑分测试。从跑分测试结果来看，性能还是蛮强劲的。
如果你使用的是全新的主机，那么你需要安装几个模块：
yum install make
yum install gcc
yum install perl
yum install perl-Time-HiRes
安装好模块以后，然后再执行下面的操作：
#wget https://byte-unixbench.googlecode.com/files/UnixBench5.1.3.tgz
#tar -zxvf UnixBench5.1.3.tgz
#cd UnixBench
#make
#./Run
敲完这段命令，等半个小时......如果你也在使用MediaTemple GS，也可以测试一下。因为是集群，分配到的服务器繁忙程度不一样，跑分上会有差别，我测试了两次，分配到两台不同的服务器上，跑分差10%左右。总体来说524.8的分数还算不错了。
