Has anyone used Alternative PHP Cache:
http://pecl.php.net/package/APC
with mediawiki?
I just installed it on a wiki and noticed about a 30% improvement
on serving the Main page. Also, what utilites are you using for
benchmarking speed optimizations? I just wrote a simple script
to parse the returned Main page for the "Served by" line and
used the time reported there. Is this legit?
