Spare-threads are idle threads. We want a few idle
threads to quickly answer incoming requests. We don't
want too many idle threads, or else we can negatively
impact performance. So, we can represent the config
below with this pseudo-code in an attempt to make it
more clear:
// Max spare threads
while ( IDLE_THREADS > 20 ) {
server.killThread();
}
// Min spare threads
while ( IDLE_THREADS < 5 && THREAD_COUNT <= 200 ){
server.spawnThread();
}
