More importantly, mount your dev filesys with atimes disabled and ext3 indexing on.

Use tmpfs for /tmp, /usr/tmp, /var/tmp, it uses swappable ram filesys which helps a lot too. Make sure nothing gets put in those tmp dirs that needs to persist across a reboot and limit the max size each can take to 1/2 total memory.

More memory...

As far as background jobs go, reschedule them for day time hours when your asleep ;-)

I was just wondering if there are special tricks people do that compile A LOT on centos? Do RAM disks help or something else I dont about that minimizes your compile time? I presently have and AMD x2 4800+ with 2GIG ram.

Just curious if I can reduce any more time out of my compiles.

Watch out for background processes that steal resources: Move /etc/cron.daily/ mlocate prelink to /etc/cron.weekly

Remove /etc/cron.daily/makewhatis and let it only run weekly (its already in weekly)

Open /etc/updatedb and tune it for your system: add ntfs-3g or vfat to prunefs

If you have any mock partitions, add that to prunepath
