huzheng commented on HBASE-17645:
---------------------------------

So ,  if oneCon flag is false.   we could just pass a null Connection object , instead of a created Connection ?

> In PE tool we have the option of using one connection for all threads. By default it is false. And you can see a  big difference in the measurements that the tool produces and also the load that it generates on the server side when this oneCon is false/true.
> Also if you see if oneCon is false, we still create one connection for initilaizing the threads and again that connection is overwritten when the threads actually starts running by creating a connection. I think we can do some clean up here.
