> With off-heap caching now the default and with auto-flushed memtables demonstrated to do a good job with smaller heaps, I think it's time to reduce heap sizes to decrease GC pause times.
> How does this sound?
> - half the ram, up to 512MB, or
> - 1/4 the ram, up to 4 GB
> i.e.:
> max(min(1/2 ram, 512MB), min(1/4 ram, 4GB))
