Which client API?

Which server version?  server OS?  epoll?

Compression on or off?

Did you time requests thousands of times and average?  8-45 ms alone is
just noise.

Even if memcache were a bit slower than MySQL (which it's not), you'd
still win because memcache never blocks.  Did you test your application in
parallel (say, 50 simultaenous clients doing 500 requests) or just one
