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.

We haven't seen that in our tests. Suggest bisecting to figure out
what changed it for your workload.

Should probably use this instead. All benchmarks show it¹s faster than
anything that has ever been written before.

Thrift? Native?
If Thrift- what threading model?

yes, that fixed it.
2.0 is considerably slower then 1.2 for cpu bound tasks, average
throughput is -15% at 50 threads.
2.0 with 20 threads burst thruput with is just 1/2 of 1.2 at 50 threads.

If you're using ccm this can happen. Make a conf/triggers directory and
that will fix it. We fixed this in trunk already.
