Hi All,

The following article describes how to use sFlow instrumentation in
Memcached to identify the top keys responsible for cache misses:
http://blog.sflow.com/2010/10/memcached-missed-keys.html

For anyone interested in trying out sFlow in Memcached, the patch can
be downloaded from github:

Cheers,
Peter
