Subject Re: Apache Cassandra 2.0.0 rc1

I've seen similar slowdowns in 2.0 - roughly the same 15%.

For instance, http://i.imgur.com/Qi6oo62.png

That's a comparison of 1.2.6 to 2.0beta1. Ignore the lines that say
speculative_retry=95percentile and ALWAYS.
Default 1.2 beats Default 2.0 in overall operation time.

Bisecting the cause of the problem is on my TODO list.
