-------------------------------

[~ywang261] Thank you for jumping in. You figured the back-to-back marking cycle just be looking
at G1GC log emissions? What G1GC configs were working for you at 120G heap? Thanks.

> I just stumbled across MemStoreChunkPool. The idea behind is to reuse chunks of allocations
rather than letting the GC handle this.
> Now, it's off by default, and it seems to me to be of dubious value. I'd recommend just
removing it.
