HOWTO: Improve your disk performance

Posted by Jason on Monday March 19, @03:25PM
from the Go-Dog-Go dept.
When you install FreeBSD, the filesystem is set to a synchronous ufs (unix filesystem). You can improve your disk performance by changing it to ffs with softupdates. It's easy!

To change your filesystem to a ffs (fast filesystem) that uses softupdates, perform the following tasks:

[Boot in single user mode]
(Press the space bar at the 10 second countdown on startup)

Type:
boot -s
Press enter for the default shell

[Run the tunefs command]

Type:
tunefs -n enable /
tunefs -n enable /usr
tunefs -n enable /var
tunefs -n enable /some_other_fs

[Reboot]

(note: you should have FreeBSD-4.1 or greater, otherwise you have to compile a custom kernel with softupdates)
