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. ** Martin 2014-10-28 0:07 GMT+02:00 Yu Zhang : > Martin, > > It turns out I am not allowed to download or read the source of Zing.
