Hi Steven,

I would really like to see measurements on that.   Do you have any
graphs that show the performance differences between single-threaded
and multi-threaded implementation?

As a general point, as  more and more CPUs are multi-core now or
provide hyper threading, you get better resource utilization by making
your applications multi-threaded.    Libevent allows you to run
multiple event loops, so that you can have at least one per core.

Niels.
