G1gc compaction algorithm

[Martin Makundi]

Hi!

It is not open source, so source is ofcourse not available.

You can ask for evaluation version if you want to run the jvm against your
pre-existing test cases, so you can see for yourself how it performs.

My experience is very positive, practically all problems are gone and I
spend zero time tuning it.

This is quite significant considering that I would previously spend couple
hours each day tuning and analyzing g1gc, quite a cost saving 20 days per
month couple hours of work.

Most significant benefits are:
- no tuning needed
- no Full GC:s any more, longest delays are couple of milliseconds (!!)
- it has built in monitoring (zvision)
- http://www.azulsystems.com/products/zing/technical-case

My life has changed from day-in-day-out dabbling in quicksand into resting
on a hammock, so I really recommend trying out Azul's Zing and learning
from it.
