"So in common practice, each worker will have a moderate size of executors,
neither too small, nor too big."
I agree on this. But what size is considered to be too big or too small.
Should 36 be too big? Only a few executors failed to heartbeat to nimbus, the
whole worker will reload.
Besides, By using a SHARED threadpool(its default size is 1) among all
netty client within a worker, the netty threads number do not increase as total
worker numbers increase. Check [jira][storm-12]. So, increasing worker count
may not cause netty context switching problem.
"3. More outbound acker message count. Usually we will allocate one acker
to one worker."
But you allocate 48 ackers to only 4 workers.
