According to your parameters you have 2 pools of 1000 threads each.

I'm not in the mood to go down that rabbit hole, so let's say that for
a miss or a pass it's the case. Keep the default max, monitor/graph
the number of threads and see for yourself what you need. It may
depend on how the clients and backends typically behave so there's
no magic recipe.
