You should also consider running two Radiator processes on your radius host,
one for authentication and the other for accounting, like this:
# authentication only
AuthPort 1645
AcctPort
# accounting only
AuthPort
AcctPort 1646

It is certainly our intention to add multi-threading support to Radiator.
However, as Radiator is written in Perl, the threading support must come from
the underlying Perl implementation, and still as of Perl 5.6 threading support
is labelled as "EXPERIMENTAL - NOT FOR PRODUCTION DEPLOYMENT". Therefore in the
interests of stability and reliability we are not yet providing a threaded
version of Radiator.
BTW - there is a "Fork" parameter, however the processing overhead is
considerable and should not be used in a busy environment.
On this topic however, many of our customers are using UDP redirectors in front
of multiple Radiator hosts as an alternative way of providing more processing
power (and added redundancy).

I usually use "netstat", but I don't know if there is something better.
