uname -a:

Linux squid 2.6.29.6 #4 SMP Thu Jan 14 21:00:42 BRST 2010 x86_64
Intel(R) Core(TM) i7 CPU @ 9200 @ 2.67GHz GenuineIntel GNU/Linux

  I'll run these tonight.

  I thought that, but actually both top and free -m tells me the same thing:

             total used free shared buffers cached
Mem: 7979 5076 2903 0 0 4144
-/+ buffers/cache: 931 7047
Swap: 3812 0 3811

  Swap isn't even touched...even when slow.

  But if you think vmstat and iostat can help, I'll run them no problem.

  Thanks,

Felipe Damasio
