I don't have any hard numbers at the moment, but I was playing with
memcache at one point and discovered something surprising (and
disheartening about PHP); Caching arbitrary objects with memcache
(within a single request) was faster than using a PHP associative
array as a cache! Memcache is wicked fast.
