> URL: https://issues.apache.org/jira/browse/CASSANDRA-5933
> Project: Cassandra
> Issue Type: Bug
> Reporter: Ryan McGuire

>
> Over the course of several tests I have observed that 2.0 read performance is
> noticeably slower than 1.2
> Example:
> Blue line is 1.2, the rest are various forms of 2.0 rc1 (I've also seen this
> on rc2, just don't have a good graph handy)
> !1.2-faster-than-2.0.png!
> !1.2-faster-than-2.0-stats.png!
