Hi samiyuru, According to the Disruptor architecture it is written such that to minimize thread switching .If we define high number of threads in Executor Service than no of EventHandlers then it will only pick threads equal to EventHandlers.If particular thread blocked then that EventHandler also get blocked. So due to this reason we should not do any blocking operation inside Disruptor Handlers.So particular EventHandler is always bound to particular thread in ExceutorService for EventHandler life time.So I think configuring threads on Executor service may not have significant improvement.
