Centos5.5 64-bit improves SATA Hard Drive Speed

During installation, do not press enter directly, enter the following string, and then install (this can increase the speed of formatting the hard disk)

Boot:Linux all-generic-ide irqpoll

After installation, modify the/boot/GRUB/menu.1st file and add ide0 = noprobe to the Kernel File (in the same line ).

CD/boot/GRUB

VI menu. lst

 

Kernel/boot/vmlinuz-2.6.18-194.el5 Ro root = label =/rhgb quiet ide0 = noprobe

Modify the device and map files, and change hda to SDA. The modified files are as follows:

VI device. Map

 

The data transmission volume of buffered is increased from 4 MB only when hdparm-Tt/dev/SDA is used, as shown below:

[Root @ localhost ~] #Hdparm-Tt/dev/SDA

/Dev/SDA:
Timing cached reads: 29800 MB in 1.99 seconds = 14938.75 MB/sec
Timing buffered disk reads: 316 MB in 3.01 seconds = 104.89 MB/sec

Adjusted speed:
