Strange performance numbers

[Ryan Mack]

I'm using memcached for the first time tonight.  I have a page with two DB
queries.  Without memcached at all (not in the code at all, requests take
12ms.  With only the first query using memcache, requests take 10ms.  
With only the second query using memcache, requests take 8ms.  With both
queries using memcached, requests take 45ms.  This makes no sense to me at
all.  Am I doing something wrong?
