[sakai-pmc] Sakai 10 update: trunk branched to sakai-10.x (r306122); trunk now 11

Tue Feb 18 06:55:04 PST 2014

FYI on the Sakai 10 and 11 trunks that I noticed this morning while profiling.

Current permgen used (without OSP): 282 MB
Current running trunk (unloaded and without primed caches): 281 MB
In other words, we now use more memory storing classes than we use to
minimally run Sakai. Roughly a 10% increase over 2.9.

Largest jars in shared (not exactly related because of how
classloading works but FYI):

It is probably not ideal that we are using a few hundred MBs to
maintain idle state on an unloaded unused system either.
Probably not something we need to spend time on but just something to
be aware of.
