Memory usage

[Roll, Kevin]

We have encountered OutOfMemoryErrors on our Sling server under heavy usage. 
Unfortunately we need to run on old 32-bit hardware in the field that does not 
have a lot of memory. I am disabling Lucene because our app is focused on 
images, not text, and Lucene seems to consume a lot of memory. Are there any 
other things I should consider that would make a substantial difference in 
Sling's memory consumption? Bundles I could remove, settings I could tweak, 
etc? Thanks!
