 Also in the squid.conf:

   acl toSquirm url_regex ^http://www\.google\..*/(search|images)\?
   url_rewrite_access allow toSquirm
   url_rewrite_access deny all

 ... will make Squid not even bother to send URLs to Squirm if they wont
 be changed. Meaning your total traffic can be higher and not bottleneck
 at the URL-rewrite step.

 You could. Squirm is faster than the perl alternatives IIRC.
