Hi Great suggestions here, as test you can try few more things: disabled log analysis, deactivated any unused probes, disabled Profiler Forwarder Persistence queue, disable ISE Messaging Service.

Hi @palani2010 ,

to check and understand the reason of a High Authentication Latency, you must "dig a little bit more":

1st, in Dashboard > Alarms, click the High Authentication Latency:

2nd, in the new window, a List of Hight Authentication Latency will open, click the Details icon:

3rd, in the new window, search for the Hight Authentication Latency issue, in this simple example: EndPointPolicy.

Hope this helps !!!
