> There are some workloads where commit log replay will run into contention issues with
multiple things updating the same partition.  Through some testing it was found that lowering
CommitLogReplayer.java MAX_OUTSTANDING_REPLAY_COUNT can help with this issue.
> The calculations added in CASSANDRA-6655 are one such place things get bottlenecked.
