Re: [squid-users] Squid uses all the cpu

Hi Bill,

I have had this problem recently. Squid ran fine ... till I added an
extensive blockinglist based on regex. When I started Squid with that
filtering list the CPU usage went up && up && up.

Extansive ACLs can also be the cause. It is recommended that you compile
squid with the btree option when you are going to have such, although nobody
ever could tell me how to make use of the betree / how to set this option.
