Wow. That is one noisy command!

java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
It looks like Java is correctly determining that this is in-fact a
"server." It seems to start with an Xmx of 25% of the RAM or around 7GB.
So, in addition to tweaking GC I'm going to increase Xmx. Any advise as to
how much memory should go to the Heap and how much should go to the OS disk
cache? Should I split it 50/50?
Again. Many Thanks.
