[Opensim-users] Hosting a medium-sized grid (UNCLASSIFIED)

We allocate 64Gb of ram to each of our MOSES VMs and rarely see more than 30% 
utilized under load.  Referring to the attached screenshot, you can see the 
first VM is only using ~8Gb ram with 10 sims allocated to it.

chances are even if you had 128gb ram, linux would allocate most of it and on 
the surface it will look like its being used, but the cache is low priority 
and anything requiring more memory will instantly take from the cache pool, so 
yes you have 5.2gb available for the system to use still.

	Those 5.2 G are allocated and not used?
