freeradius -> AD performance

20 Dec 2019

      I would like to replace the windows NPS service with freeradius.
Freeradius provides a lot better visibility and control than the Microsoft
NPS service.  However, doing some very rudimentary performance analysis and
my freeradius server is ~4-5times slower than the Microsoft NPS service.

My wireless controllers provide a "test your radius server" command and it
outputs the response time.  I am testing using a known bad username and
password against both radius servers.  According to the wireless controller
the MS NPS returns a result in ~3ms, while Freeradius returns a response in
~1000ms.  The NPS server I am benchmarking is in production and under load
while the freeradius server I am testing is not.

Below is the output of freeradius -X as well as an example query.  If
anyone sees anything that might explain the ~300% performance difference,
I'd appreciate it.
