srcdomain will add some occational latency as Squid then needs to lookup
the domain of the requestor. Other than that such small ACL's should
only have a marginal impact on performance.
You may expericence performance problems if you are using very large ACL
lists, such as a url_regex list of thousands of entries. The performance
penalty varies a lot depending the type of ACL used and the size of the
list.
