Alaine - Awesome information!!!
I had made some changes before seeing your email.
Current setup
CMS
16G heap
6G Eden
I also reduced Initiating Occupancy from 75 to 60. The thinking was that GC
will happen sooner giving me room for a burst to let GC catch up?? Maybe
that's completely wrong thinking
THIS! A well-reasoned and clear explanation of a very difficult topic. This is
the kind of gold that a user mailing list can provide. Thank you, Alain!
