Re: [squid-users] process load

Hi,

Adrian though being a newbie I know about that though not perfect :D.

I basically have 2.5 Ghz computer with 512 MB ram. With those number
of users hunting squid, how many DSTDOMAIN ACL are considered safe.

I know I can check the process load by adding few ACL at a time. But I
can't complain management each week to replace the CUP or memory.

So I am here for the help. You guys must have hell lot of experience
to tell me that in rough figures.
