[VDT19] Concurrent Garbage Collectors: ZGC & Shenandoah by Simone Bordet [IT]

[@vahidsadeghi5491]

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

[@purpleblck]

Excellent job, but I'd wish there were more materials on this topic, especially for the general public (a.k.a. "rookies in GC").

[@daxinfeng2689]

Excellent speech！

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?

Great talk.

Particular interesting how the 64 bits Platform only use 44 bits, I guess no body has more than 16 tera on a single box.
