I am seeing almost 99% of thread in park/wait condition and 1% in running out of threadpool of size 100. CPU usage is 25% and memory just 2GB out of 6 GB allocated. Should I increase threadpool size? I think so because system has enough resource and more threads will utilize it properly to increase througput.

If almost all threads are waiting or parked, I would say you have issues with concurrency in the application and adding more threads won't help. Or there are already more threads than needed. – Sami Kuhmonen Jul 10 '16 at 06:57

I guess there are already more than required thread. Its just that load on my application vary too much .Its 4x vs x in peak vs low time and I need to have more threads for peak time. – Rakesh Jul 11 '16 at 09:37
