拿到vps之后要看下它的性能，这样才能更好的使用。

硬盘IO性能：
方法一 4096+0 records in 4096+0 records out 268435456 bytes (268 MB) copied, 9.82702 seconds, 27.3 MB/s 网上说一般要大于10M的基本可以使用。
方法二 /dev/sda1: Timing cached reads: 21896 MB in 1.99 seconds = 11006.64 MB/sec Timing buffered disk reads: 156 MB in 3.01 seconds = 51.84 MB/sec hdparm命令用于测试硬盘cache和硬盘device的读取时间。可看到这次disk的读取速度是51.84MB每秒。
方法三 4096 bytes from . (ext3 /dev/root): request=1 time=0.4 ms 4096 bytes from . (ext3 /dev/root): request=2 time=0.4 ms 4096 bytes from . (ext3 /dev/root): request=3 time=0.5 ms 4096 bytes from .
