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
