How to speed up your hard drive on Linux
Linux servers usually use conservative default IDE driver settings that could be significantly slowing down your system. By default they are set to most safe settings guaranteed to work.
To get faster 32-bit file transfer on your hard drive, you can use HDPARM command. It 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.
You can add the following line to your Linux bootup script:
Edit /etc/init.d/boot.local and insert:
hdparm -c3 /dev/hdX*
Where,
* X is your HDD number
* c3 is I/O support set to 3 – turn on 32bit transfers
Personally I did a quick test:
