I don't have hard numbers, unfortunately. It also depends on the number, and kind of queries the server does for each request. If you do a simplistic analysis, you could assume that the two processes are simply stealing CPU time from each other. If I recall my numerical analysis courses... E = # of EAP requests/s (say 30 on a normal machine) Q = # of SQL qeuries/s (likely 1000 un-cached on a normal machine) Assuming one SQL query per EAP transaction, we have 'E' SQL queries/s. So E/Q = 3% of CPU time is being used for SQL. That is stolen directly from EAP requests, so there is 97% CPU time left, or .97*30 = 29 EAP transactions/s as a theoretical maximum. Realistically, there is a lot more overhead than this. But I would be surprised if it lowered the maximum number of EAP sessions by more than 10-20%. Alan DeKok. - List info/subscribe/unsubscribe?
