Why would SQL_NO_CACHE slow it down? By not checking the cache or storing
the resultset into cache it should be quicker, at least a little bit.
Unless, of course, the query would always return the same result set. But
with count(*) in there it might not. In fact, I believe the count(*) would
prevent MySQL from caching the query in the first place, like using now() -
it's a non-deterministic function.
