I'm looking to compare our existing NPS authentication environment with our new ClearPass appliances, in particular authentication performance. I've set up some basic RADIUS monitoring of both solutions and it appears that the NPS servers respond significantly quicker than the ClearPass appliances.
I appeciate the CP policies can be a little more complex than NPS, but my tests use the most basic of user authentication settings. So, is this expected behaviour? Perhaps the AD lookups just aren't as responsive? If not, are there any settings that I can investigate to troubleshoot the response times? I've checked network latency and it isn't the issue here.
