It might be interesting, sure, but it's not quite apples-to-apples since
those are n separate caches that don't interact with one another at all,
whereas an n-threaded instance is a single interface to a single cache.
Also, that requires a different code path on the client side (multigets
will need to be split among multiple servers) which might affect the
benchmark results.

But sure, wouldn't hurt to see that as well.
