Hi! You shouldn't set thread pool size to such high values. It's recommended to leave it default (number of available cores), or 2 x number of cores.
> I found Public thread pool idle numbers on every node is always 0 What do you mean by that? How did you check it? CPU load may be low, if tasks, that you run, are sequential and cannot be parallelized. Make sure, that all threads are not waiting for each other and they are actually doing usefull work.
