edit /etc/sysconfig/memcached (or wherever 'grep SYSCONFIG
/etc/init.d/memcached' tells you to find your configuration file; dunno
if it's different on ubuntu - I use CentOS) to specify CACHESIZE="8000"
for 8GB.  (or should it be 8196?)

you have stats for number of sets, gets, cache_hits, and evictions,
which probably are what you're looking for.
