May I propose to use MurmurHash instead of MD5 for Ketama hash algorithm ?

MD5 avalanche behavior is OK, but under heavy load, it could become slow and / or too consuming ...
MurmurHash is not a crypto hash function, but is really fast and had a very good avalanche behavior.

There is already an open source (public domain) Java implementation here : http://dmy999.com/article/50/murmurhash-2-java-port

General info available here : http://en.wikipedia.org/wiki/MurmurHash
