Hi:
I am not at all familiar with jmemcached, but I took a quick look at
the code and from what I can tell, max memory defines the total number
of bytes allocated to the cache and the 'ceiling' is used to control
when items will be evicted from the cache. Once the total amount of
data in the cache exceeds maxMemory - ceiling, it will start evicting
items from the cache. So, for example , if I define maxMemory to be
1,000,000 bytes and define ceiling to be 100,000 bytes, once the total
number of bytes in the cache exceeds 900,000 bytes (1,000,000 -
100,000), it will start to evict items.
Hope this helps

All,
I'm setting up the running of the server portion of jmemcached. It
takes a couple of arguments including:
-c ceiling memory to use (default .976M)
-m max memory to use (default .062G)
the default values confuse me and make me thinking I am interpreting
these values incorrectly. Can anyone help explain these values? I
would have thought that -c would be much higher by default - so I'm
wondering what "ceiling" means in this context...
Help!
