The standard redirector interface is a bit inefficient and you need a
number of children depending on your load, or else Squid will consider
the helper overloaded and get very upset..

If you are worried about performance then I would recommend you to try
looking into using Squid acl's instead. Give you nearly the same pover
at only a fraction of the per request performance penalty.

Note: In both Squid and SquidGuard you should avoid regex patterns as
much as possible. Use structured acl types such as dstdomain.

You probably haven't build the SquidGuard DB files.. see the SquidGuard
documentation on how to use DB files which radically speeds up startup
and reduces memory usage considerably for large lists.
