All I am showing is a very long chain of method calls for Jersey that seem to 
compose most of the overall time.

I suspect that the tests Mark was talking about where he got 50k requests did 
not have anything like what I am seeing.
Just shows Jersey is not capable of high throughput.

What are we looking for here?

I don't know if there's any optimisation possible in the
SocketProcessor.run() method in Tomcat.


If I were to consider what Jersey is doing, I'd look at why there's an
expensive ContainerResponse.write() call (costing 0.6ms) while it still
seems to be processing the request.
