Ok. I will look into fedoralegacy because I'm running the latest kernel
from the mainstream updates.

Maybe it's because my machine has only 256MB ram? I think these values
are computed according the RAM present.

No, I don't run p2p... What causes the most traffic is a lot of hosts
with NFS (udp) mounted shares which reside on the other side of the
firewall so there's a lot of traffic. Also I run shorewall 2.4.0...
Could it be slowing down the cleaning of the cache?
Thanks for your help.
