Hi All,  
I've been using ES for a while and I'm really enjoying it, but we have a  
few slow calls in our code. I have a few hunches around the code that's  
using the client inefficiently, but I would like some definitive proof.  
I've attempted to profile our application using YourKit when we're load  
testing, and I've found we're spending 30-35% of our "wall time" in the  
Netty classes of the ES Node client. However, I can't tell where the call  
is originating from in our source, since the calls are asynchronous and I  
can't capture the stack. Are there any debugging options I can turn on in  
the client that will help me with profiling so that I can track down the  
code in our system that's not using our client efficiently? Any help  
would be greatly appreciated!

Thanks,  
Todd
