I believe we're somewhat constrained by our license with Oracle regarding what we can publish for benchmarks. But others are not, and this piece by Mike McCandless gives some good insight into what's possible with Zing:

As at least some of you have figured out, the title is incorrect. Azul did not make Zing open source; we are just making free licenses available to developers working on open source projects.

Regarding performance, you can find some useful information on Azul's website. In a nutshell, Zing's strengths are its ability to GC while the application continues to run; and its ability to support very large memory heaps without a performance penalty. The two combine to permit a single JVM to do a lot more work and to avoid long application stalls when GC is triggered.
