CentOS is Linux ;-) so I will look into getting oprofile setup in our sandbox environment and hammering away as a first step. Also, what do you consider "lots" of regex rules? I have about 20 or so rules that match on req_header with a regex of .* (i.e. does this header exist) and then around 150 lines in some files that match Via and User-Agent headers. A quick search for "squid gnumalloc regex", etc. etc. didn't yield too many useful results. Can you clue me into the problems (and solutions!) you're referring to? Is it gnumalloc or the regex that is the problem? Is dlmalloc the solution? Thanks, Tony
