I tested this on our cluster, and the result are below:
Before remove sleep in connect

After remove sleep in connect

After remove sleep in connect, we got more than 100% speed increase, the
most important thing is that failed Client will never bind send message to
other worker anymore;
@clockfly will you test this on your cluster and give some advise.
