I wanted to ask this community about typical results for ClearPass's RADIUS Request Processing time. I have attached an example of what is now typical for me:
I have been trying to get this number down as low as I can, because in one of the "frequent disconnect" threads, one user was able to mitigate that problem by reducing the amount of time for RADIUS responses. Last semester I was seeing it more between 1k and 2k, but it still spikes to that at times.
My questions is this: Is between 1000 and 1500 ms a good overall RADIUS response time, and if not, how do I find the culprit. The Monitoring » Live Monitoring » System Monitor screen shows all items under the ClearPass tab as taking between 1 - 2 ms, so where does the extra 500 - 1500ms on this chart come from?

If it's normal, let me know, and I'll rest easy :)

The SAN is brand new and quite underutilized, but I can ask them to try it on the measure the IO and IOps.
Here is a screen shot from that END-to-END screen that shows some request counts:
Also, Danny, I did get the breakdown numbers from those charts. As I said in my original post, they were all between 1 and 3 ms each, but the total is 500-1500.
