performance of NPS .. need to know if my info is normal RRS feed

  • Question

  • We are discussing internally to moving our current single NPS server to multiple NPS's with 2 NPS proxies.

    The reasoning behind this has mostly been to increase redundancy. However I have been curios if we even need to go that route because no one is really sure if our existing NPS server is overloaded or not. So I began running performance monitor and tracking the "NPS Authentication Server" counters. I collected data for 4.5 hours on a typical data and these are the numbers I got. I'm wondering if these are normal or extremely high for our environment.

    ~120 access points spread over 6 buildings.

    ~1000 users on wireless at any given time

    NPS is running on 2008 R2, all DC's are 2008 R2.

    NPS Data (4.5 hours runtime)

    Access-Challenges/sec - avg = 1.5, max = 45, total = 2,339,207

    Access-Requests/sec - avg = 1.7, max = 51, total = 2,672,590

    Access-Accepts/sec - avg = .198, max = 6, total = 325,000

  • Hi,

    Thanks for your post.

    Did you get any error under this workload? Not only authentication packets, you should also monitor the machine performance of NPS server. If all things doing well, you do not need to worry about.

    Please check the following article for best practices of NPS.

    In addition, you can deploy RADUIS/NPS proxy server to implement the redundant. You need define the connection request policy, so it will forward the authentication requests to the proper NPS server.
