Hi, I'm hoping to get some help on how to help tune our 1.0.x cluster w.r.t. 
row 
caching.

We're using the netflix priam client, so unfortunately upgrading to 1.1.x is 
out 
of the question for now.. but until we find a way around that, is there any way 
to help determine where the 'sweet spot' is between heap size, row cache size, 
and leaving the rest of the ram available to the OS?

We're using the oracle jvm with jna so we can do the off-heap row caching, but 
I'm not sure how to tell how much ram it's using, thus I'm not comfortable 
increasing it further. (currently we have it set to 100,000 rows and we're 
already seeing ~85% hit rates, so we've stopped upping it further for now).

Thanks for any advice,

-Josh
