Well we get about 30,000 page hits PER SECOND.
So we have a template engine that generates a page using PHP/MySQL and
populates it as everyone else does with the generic content.
Then we store THAT rendered page in a cache (memcache pool as well as a local
copy on each server).
HOWEVER, there are of course dynamic parts of the page that can't be cached or
we'd be making a cached page for every unique user. So things like their <?=
$username ?>, or maybe parts of the page change based up their membership <?php
if ($loggedin == true) { ?>, or maybe parts of the page rotate different
content (modules if you like).
Therefore we are trying to mininimize/compress the cached pages that need to be
served by removing all <!-- --> and /* */ and // and whitespace and other
stuff. When you have this much data to serve that fast, those few characters
here and there add up quickly in bandwidth and space. As well as render time
for both apache and the client's browser's parser.
