Hi tachu,
You may want to consider how the objects are fitting into the slabs.
For some reference material, see the links off of:
http://code.google.com/p/memcached/wiki/FAQ#How_does_memcached%27s_memory_allocation_work?_Why_not_use_ma
"stats slabs" may help too.
Also, be aware there is some memory usage for CAS. If you're not using
any CAS operations, you can save some memory with the -C flag.
