performance regression with 0.10.2.0 client talking to 0.10.0.1 servers

[Alex Cozzi]

I noticed a significant reduction in throughput when I upgraded my app to 
0.10.2.0. I am talking to 0.10.0.1 server and I wanted to take advantage of the 
compatibility of the newest release with old server, but I noticed that my 
performance went from 20K msg/sec to 2K msg/sec in one case and from 9K msg/sec 
to 4K msg/sec in another case.
Is this expected or should I file a bug?
