I have two memcacheds setup to use 512MB, one has been running for about =
one month, the other for only a week. But no matter how long they're =
running, they stats command never shows them using more than ~370MB of =
memory to store items. Is this because memcached is reserving this =
memory? Or is this memory used for other purposes to handle the storage =
of these items. I show the memcacheds using just about all 512MB in the =
operating system, but they never seem to get close to the =
limit_maxbytes. Each server has anywhere from 1.3 to 1.4million items =
currently stored in it, under curr_items. Does that mean there's =
roughly 114 bytes to store each item in the daemon?
