I noticed that it not only affects this branch, but also the master branch.  Here are the comparison on my laptop for running the perf test with only 5,000/sec throughput with code from master.\r\n\r\nBefore (git hash: 3db968092077363bd766db516b9e1135273672bf)\r\n[netty3-r5000.txt](https://github.com/apache/storm/files/146057/netty3-r5000.txt)\r\n\r\nNow (git hash: bd396b3a4ec0c242f18725ddf43e35f26da51269)\r\n[netty3-new-r5000.txt](https://github.com/apache/storm/files/146058/netty3-new-r5000.txt)\r\n\r\nNote: when running the latest code, my CPU is almost 100% busy which may explain why it was so much worse.
