Thank you Val.

Another question is that although the reported off-heap memory is not big 
(around 72M), I observed big heap memory consumption - some as high as 6G. I am 
not using any expiry policy. Is this normal?

Hi Shaomin,

1. Yes, this is a per node setting. So if there are two nodes on one box, it's 
possible that 20G will be allocated on this box. You should make sure that this 
limit correlates with the amount of physical memory you have.
2. In 1.5. IgniteCache.metrics() return values for local node only, but you can 
use IgniteCache.metrics(ClusterGroup) to get aggregated values for a set of 
nodes. This is already fixed in master - in 1.6 aggregated metrics will be 
returned by default.

-Val
