[VDT19] Concurrent Garbage Collectors: ZGC & Shenandoah by Simone Bordet [IT]
Ғылым және технология
Java 11/12 offers 2 new Garbage Collectors: ZGC and ShenandoahGC. The main goal for these two new GCs is to reduce GC pauses to only few milllisecond and possibly to less than a millisecond, therefore solving once and for all the GC pause problem. This session will present these two new GCs, how to enable them, how to configure them and will discuss their performances.

It's the clearest presentation about the GC types.
Oh man, this is pure gold. Clears so many areas not inferreable easily by GC docs
Great speech! Very interesting subject
Excellent job, but I'd wish there were more materials on this topic, especially for the general public (a.k.a. "rookies in GC").
Excellent speech！
Great talk.
great to learn about gore internals
I am still looking for benchmarks comparing ZGC and Shenandoah 2.0 with more than one metric. Pause times are mostly good for both, throughput also seems to be in-line more or less in case you have spare cores that would otherwise be idle (-10% compared to parellel). However what I haven't found at all is a comparison of e.g. total instructions executed / cycles consumed / total energy used for a particular load type - all the benchmarks I saw used spare cores available which might not be the case in the cloud / on high-load servers in clustered environments / in VM environments.

Did you manage to find it?
Particular interesting how the 64 bits Platform only use 44 bits, I guess no body has more than 16 tera on a single box.
