-------------------------------------
Hello [~lgoldstein] if I am disturbing you with my questions, I am sorry but I
am not able to sit still unless I am able to decipher how the threads are
working, and what does the thread dump means (in the screenshot attached)
Need your guidance, as understanding it is a bit tricky

> IoServiceFactoryFactory ==> *NIO2, MINA, NETTY*
> How does this works internally, and how performance will be affected with the
> different IoServiceFactoryFactory.
> We did lots of performance testing and found NIO2 is the best performing of
> the 3? Why is it the best of the other 3, and why Apache selects it as
> default.
> How does NIO Worker Threads affects the performance. Attaching a screenshot
> from the thread dump which I took

> All the threads in park state, and some are in runnable in different phases
> of execution. I am not able to decipher what does the stacks mean:
> The details which I got are (*PARKED*):
