How many authentications per second can Clearpass manage?

I'm after an estimate of how many user authentications per second Clearpass can manage.

 

And just to be clear, I class a 'user authentication' as a full EAP exchange of a dozen Access Requests, Challenges etc. We currently peak at about 70 'user authentications' per second which equates to about 750 Access Requests per second. 

 

The authentication is against AD in our case,  but even a general idea against an arbitary back-end would be appreciated. 

 

Thanks,

A 25K appliance can handle between 250 and 300 authentications per second reliably.

 

Many times authentication performance issues are with AD not being able to keep up.
