Roland,
We found Linux was 3x faster than Solaris, apparently due to CPU clock
speeds.
This test did not involve database calls or accounting. It had a tiny user
database.
So this test basically measured just the performance of Radiator
authentication.
The clients were pounding it from remote machines.
However, we did not test Solaris x86 or Linux on SPARC (if this port
exists),
and so cannot be sure clock speed solely explains the difference.
It could be the OS or the perl impl make a difference.
It may also be the dual processors on the Linux box made a difference.
That is, although radiator is not threaded, the second processor may have
been used for i/o, ipc, etc.
We did not test NT.
We are deploying on Solaris rather than Linux only because our colo site
does not yet provide full support for Linux.
But our plans are to use Linux as soon as possible due to the performance
differences and costs.
We find administration of Linux easier than Solaris for the software we use
on Linux for the radius servers.
But this is only radiator and perl in our case.

We have customers running all three of these environments, and all perform
well. We have done some comparative performance testing and there are some
numbers in section 23.0 of the Radiator reference manual. There are also
some
descriptions of a few customer installations at the following URL:
http://www.open.com.au/radiator/examples.html
On this same topic we are still looking to add more examples to this page so
if
anyone else would like to contribute a description of their system, please
send
it directly to me (with a note stating if you want it to be anonymous or
not).
regards
Hugh
