Redhat 系统提速[原作：hotmanhh兄弟]

hdparm  provides  a command line interface to various hard
       disk ioctls supported by the stock  Linux  ATA/IDE  device
       driver  subsystem.   Some  options may work correctly only
       with the latest kernels.  For best results, compile hdparm
       with the include files from the latest kernel source code.

[root@h24-80-27-140 root]# hdparm -T /dev/hda

/dev/hda:
Timing buffer-cache reads:   128 MB in  0.39 seconds =328.21 MB/sec
[root@h24-80-27-140 root]# hdparm -t /dev/hda

/dev/hda:
Timing buffered disk reads:  64 MB in  1.39 seconds = 46.04 MB/sec


是因为RH9本身就优化了?还是因为我把X86改成X70了

ATA33 —X66
ATA66 —X68
ATA100 —X    这里应该是多少？
我查了HDPARM，里面找不到说明。

是X69。

能在這裡看到這篇 3 年前的文章，感覺很好，但小弟要抱怨一下。

這一篇的原始作者，正是小弟不才在下我，但作者的名字被換掉了，不爽。
