Hi Randy, without setting max-pool-size-max (which defaults to 64) you will not be able to see more than 64 threads. May I ask why you want to create 100 threads for handling a single stream of incoming connections? I would expect at least 99 of them to be idle at all times. If you want to perform blocking operations in the flows that handle each of those connections then I’d recommend to use a dedicated dispatcher for those.
