I use this formula, found some where

cache_dir aufs /var/spool/squid C L1 L2

L1 = ((C*1000)/256/256/13)*2
L2 = 256

so with

C = 10000 => L1 = 22
or
C = 50000 => L1 = 110

is this formula reasonable ?

Before to use this formula I was using:
C = 50000 and L1 = 16
and believe me the performances were realy
bad.

Another question, if I want rise C and then L1
do I have to reinitialize ( delete and recreate )
the swap ?

Thank you
