Joshua McKenzie commented on CASSANDRA-10403:
---------------------------------------------
The debate here isn't between "Do we consider G1 or disregard G1 entirely", but
rather "Do we use CMS or G1 as our default GC for 3.0, keeping the settings for
the alternative available in our configuration files for users to swap between
easily".
[~enigmacurry]: did we ever get that 100x test run to complete successfully?
Before we determine whether Paulo should go fully down this rabbit-hole pre 3.0
releasing, I'd like that data point since we invested some effort into getting
that running already.
> Consider reverting to CMS GC on 3.0

> For smaller heap sizes G1 appears to have some throughput/latency issues when
> compared to CMS. With our default max heap size at 8G on 3.0, there's a
> strong argument to be made for having CMS as the default for the 3.0 release.
