Benchmark of client APIs per get query?

I'm curious to find out if there are any bencharks WRT client APIs.
I wrote a quick benchmark to test against my localhost running Memcached
1.1.11 and the Java client 1.1 and I'm seeing about 1ms per get().
I noted in the archives WRT apr_memcached:

Well I'm seeing < 1000 gets per second. I also see less than < 500
gets+sets per second (when I do this at the same time).
I expect some of this to be related to Java serialization.
So I have a few questions:
1. Has anyone created a client benchmark? It would be interesting to
have a basic benchmark with clients storing to localhost N bytes and
then trying to determine gets() per second.
2. How does apr_memcached store objects in memcached? Direct bytes
from memory? Any ideas why its so much faster?
3. How does the perl client store them?
