Ryan McGuire commented on CASSANDRA-5933:
-----------------------------------------

Hi [~vijay2...@yahoo.com], I'm not sure what you meant by 'custom with 5 to 10 
ms'. Can you please clarify the test scenario you'd like me to run?

                
> 2.0 read performance is slower than 1.2

> 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!
