Making Linux snappier...

Interesting article here...

To cut to the quick, add these two lines to /etc/sysctl.conf

Code:

vm.swappiness=1
vm.vfs_cache_pressure=50

Just about to try it myself!

Hi
My experience with Ubuntu is this:-
When I only had 256MB of RAM installed it was forever swapping, HDD was clunking in and out all the time. Now I've added an extra 1GB. When I look in my System Monitor I see that I seldom use much over half a gig of RAM anyway, and my 'Used swap' is 0 or some very very small value.
So I don't think that altering swappiness will have much effect for me. Unless I started using some software that was extremely memory intensive which forced swapping.
Try changing swappiness by all means, but first check whether you are actually doing any swapping at all.
Good luck.

Well, didn't seem to do much for me. I do have 1.5GB RAM & rarely use any swap though.

May be good for people who manipulate large files (video editing/transcoding etc)...
