Speed up Red Hat 9's default disk access

Recommended Posts

Speed up Red Hat 9's default disk access. To do this it helps if you have knowledge of vi (a console based text editor). As root issue this command in a console

 

vi /etc/sysconfig/harddisks

 

This will open a text file with certain settings disabled by default, we are going to enable those commands and as a result increase the speed of hard disc access in Red Hat.

 

First, lets find the line which reads as follows

 

#USE_DMA=1

 

and now delete the # so that the line now reads

 

USE_DMA=1

 

Now, scroll down and find the line which reads

 

#EIDE_32BIT=3

 

and delete the # so that the line now reads

 

EIDE_32BIT=3

 

Next, find a line which reads

 

#LOOKAHEAD=1

 

and again, delete the # so that the line now reads

 

LOOKAHEAD=1

 

Thats it, you are done, now lets SAVE our changes in vi by typing

 

:wq

 

The : (colon) allows use to 'type' a command in vi, if you see INSERT or REPLACE instead, press ESC then try again.

 

Think of the w and q as:-

w=write

q=quit

 

Once done, time how long something takes to start like Mozilla or OpenOffice. Then reboot the computer and time again, notice the difference ? ;-)
