Results attached.
With your app rps does a hell lot better and non-rps worse ;->
With my proggie, non-rps does much better than yours and rps does
a lot worse for same setup. I see the scheduler kicking quiet a bit in
non-rps for you...
The main difference between us as i see it is:
a) i use epoll - actually linked to libevent (1.0.something)
b) I fork processes and you use pthreads.
I dont have time to chase it today, but 1) I am either going to change
yours to use libevent or make mine get rid of it then 2) move towards
pthreads or have yours fork..
then observe if that makes any difference..
cheers,
jamal
