Joshua McKenzie updated CASSANDRA-7486:
---------------------------------------
Comment: was deleted
(was: Sanity check on local laptop on a variety of workloads looks comparable
between CMS and G1, slight edge to CMS but I'm on a sub 8G heap so that's to be
expected.
Couple of spelling nits in comments in conf:
misspelled "effecitve"
vice versa, not visa-versa
Haven't tested yet on CI as I have a dtest going I don't want to mess with but
I'm comfortable moving forward w/the results from testing locally.)
> Migrate to G1GC by default

> and https://twitter.com/rbranson/status/482113561431265281
> May want to default 2.1 to G1.
> 2.1 is a different animal from 2.0 after moving most of memtables off heap.
> Suspect this will help G1 even more than CMS. (NB this is off by default but
> needs to be part of the test.)
