[squid-users] cache_dir L1 L2 question

Hello,

I have a 80GB drive on a system that I would like to dedicate to a squid
server. The notes in squid.conf say that I should subtract 20% and use
that number for the Mbytes field for cache_dir. So I would have 64000.

The question is, what is a reasonable L1 and L2 to put for this setting?

Also, I don't understand the different storage types, (ufs, aufs, diskd,
etc), but for the system I want to set up, would either one be
preffered?


Thank you,

Murrah Boswell
