I'm reminded of a sales prospect from hell that I had a few months back.
He turns from looking at my portfolio of web sites, puts it down and says, "The problem with all the web sites out there .." (I lean forward, expecting to hear something profound) ".. is that they all suck. Build me a web site that doesn't suck. And can you make it so that the web site comes out at the top of the list on all of the search engines?"
Well, gee, all you had to do was ask.
All that to say (or reiterate, as it seems you've touched a nerve here today), this site hasn't been built to be slow. That's not an undocumented feature. Behind the scenes there are a lot of things going on to keep the content up to date.
If you are seriously interested in helping make Perl Monks faster, excellent!
