Eden size

Hi,

I am running a 64-bit JVM on a LInux machine with 15GB of RAM.

I have increased the Java heap space size by 16x

HEAP="-Xms8192m -Xmx8192m"

I have a feeling that I should be increasing the eden space by a
proportionate amount:

NEW="-XX:NewSize=2048m -XX:MaxNewSize=2048m"

However, the comment above the eden setting states:

"you'll need to tune this down proportionally if you modify the HEAP
values above"

Which I find confusing.

Many Thanks

Paul
