Sean Carr commented on ZOOKEEPER-545:
-------------------------------------
The default for -XX:ParallelGCThreads is the number of cores, which seems
fairly sane. There are probably some environments where that should be adjusted
but I think it's a good default for ZK.
> investigate use of realtime gc as the recommened default for server vm

> We currently don't recommend that ppl use the realtime gc when running the
> server, we probably should.
> Before we do so we need to verify that it works.
> We should make it the default for all our tests.
> concurrent vs "g2" or whatever it's called (new in 1.6_15 or something?)
> Update all scripts to specify this option
> update documentation to include this option and add section in the dev/ops
> docs detailing it's benefits (in particular latency effects of gc)
> Also, -server option? any benefit for us to recommend this as well?
