[CentOS] special tricks for developers box on centos 5

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 ;-)

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
