The fun of memcache is you can often do without that expensive database
query, so it does gets to be the bottleneck.
Our pages are completly dynamic but we (mem)cache chunks of the html.
This way many requests require no mysql query at all. Profiling showed the memcache
calls (about 4 get_multi()s per page) used > 40% of the processing time. (Which, if your pages take <30ms to build, is really not that much in absolute time)
Our perlclient rewrite did fix that :)
