Thanks Alan for the response.

I have tried PAP Authentication using users file and users stored in PGSQL Database.
With the users file Iam getting 125 auths/sec and 80auths/sec for 1000 and 10000 users respectively.
With SQL database the figures are 105 auths/sec and 70 auths/sec for 1000 and 10000 users respectively.
My query is why there is no consistency in auths/sec between 1000 and 10000 users and how to make it consistent or atleast nearby figures.

*how* are you authenticating users? are they in SQL? do you have indexes etc?
