Michael Shuler commented on CASSANDRA-11514:
--------------------------------------------
Bumped up from 10M to 25M writes/reads and this round on
[trunk_3.5_3.0-compaction_LCS|http://cstar.datastax.com/tests/artifacts/aa6dee6a-fcd7-11e5-8f8b-0256e416528f/graph]
looks like 3.5 is pretty evenly split performance-wise between 3.0 and trunk.
