Hmm, Deja Vu .. someone just took me to task on rgma on this point.
Alittle more xposting pasted in here too..
First a little more background on where I was trying to go here.
It was the contended that event-driven servers could be done
in a single-threaded and a multi-threaded environment.
No argument with this here.
One side argues that multi-threading will buy you nothing.
The other side arguing that it will perform better.

By "no difference" , I really mean that one or the other MUST be
done for you to be truly "event-driven", practicalities aside for the
moment.

Exactly.
The implication is, if my definition of event-driven systems is correct,
program control MUST be external to the procedural code of the events
for a server to be truly "event-driven".
Can it be done with a single-threaded 'dispatcher/monitor'? Certainly.
If OS multi-threading is superior to software time-slicing on your platform
then it would follow, that a multi-threaded event-driven server would
outperform a single-threaded event-driven server regardless of
how many CPUs your processor has.
Are there any faults with this logic?

Based on my definition of "event-driven", Cold would NOT classify.
It does have a 'dispatcher' which simulates time-slicing,
yet it doesn't dispatch events. It only partially approaches this at the
network level only.
BTW, if you think me too critical of Cold, its only because I like it
a lot. I'm funny this way. :-)
