Susmit Sarkar updated SSHD-1153:
--------------------------------
Description:
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 2, and why Apache selects it as default.
How does NIO Worker Threads affect the performance? Attaching a screenshot from
the thread dump which I took
!image-2021-03-29-23-52-39-814.png!
All the threads in park state and some are runnable in different phases of
execution. I am not able to decipher what does the stacks mean:
The details which I got are (*PARKED*):

For *RUNNABLE:*
