I didn't quite follow all of that, but I'll ask this question: where
does your server spend its time waiting if it has nothing to do? Mine
spends its time in a single 'select' call, which contains the fd-bits
for the main connection socket, and all client sockets. I'm not
multi-threaded, so that is easy for me to do.
What is it that "ripens" your events to trigger the polling? In general
polling (as opposed to calling the 'poll' SysV socket call), is a bad
idea, since your CPU is busy doing things without accomplishing much.
Polling is used in some circumstances in order to get the absolute
minimum latency, but that is usually in situations where the CPU is
dedicated, or when what it is waiting for is guaranteed to be ready in
a very short period of time.
My goal is that when there is nothing for my server to do, it will use
no CPU time at all. Now, the NPC's will be doing things, but in the
intervals when none of them is active, the server should be idle.
All my beliefs, anyway!
