今天学习了一个磁盘监控的的命令hdparm在服务器和自己的虚拟机分别试了一下，挺好用的在服务上面[root@oss_Srv ~]# hdparm -Tt /dev/sda/dev/sda: Timing cached reads: 13002 MB in 2.00 seconds = 6507.36 MB/sec Timing buffered disk reads: 780 MB in 3.01 seconds = 258.72 MB/sec速度很快因为是SCSI硬盘，258M每秒本地虚拟机就没这么快了[root@localhost yum.repos.d]# hdparm -tT /dev/sda/dev/sda: Timing cached reads: 7936 MB in 2.00 seconds = 3969.90 MB/sec Timing buffered disk reads: 104 MB in 3.04 seconds = 34.23 MB/sec速度很慢34M每秒。5400转的IDE硬盘速度自然慢
