Hi,
We are running Region Server on big memory machine (70G) and set Xmx=64G.
Most heap is used as block cache for random read.
Stop-the-world GC is killing the region server, but using less heap (16G)
doesn't utilize our machines well.
Is there a concurrent or parallel GC option that won't
Slab cache might help

Hi,
For a possible future, there is as well this to monitor:
http://docs.oracle.com/javase/7/docs/technotes/guides/vm/G1.html
More or less requires JDK 1.7
See HBASE-2039
Cheers,
