Hi, I am using Freeradius 2.2.0 on redhat 5. My goal was to increase the speed of user authentication. To achieve this I configured Load Balancing (with realms). I have a proxy Freeradius server, that is just proxying requests to 2 other freeradius servers. Problem is that, when i sent a specific number (10 million) requests to proxy server (that just proxy requests to 2 other servers) , it took about 45 minutes to complete these requests. But if I send same amount of requests direct to on of the server (without sending it to proxy server), requests are entertained rapidly (in around 16 minutes). Can any one please tell me , what's the issue. Thanks a lot.

you only asked this question less than 2 hours ago..... okay, you need to see why the proxy is causing a x3 factor in slowdown? run the servers in full debug mode with timestamps and check to see where your delay is....dont throw 10 million requests at it though, just a dozen should be enought in the first instance to see where the hit is. I'd assume that you havent made any configuration changes or tweaked any configs...in which case your proxy box is probably not ready to be dealing with that many in transit requests (whereas the authentication servers can handle multiple requests per thread) - so, some basic tweaking will probably do something.... ..though I think you've already found that you dont need to load-balance ;-) alan
thanks alan Actually I am using load balancing for rapid authentication of users. let suppose i have one prosy server that is proxying incoming requests to these five servers. Theoratically the speed of authentication should be fast. But in case of mine it is too slow. I have changed 'max_requests' in radiusd.config. And also remove unnecessary processing on radius server (that is proxying requests). Now tell me what else can I do?? :( Though i am a new bee in RADIUS, but I think Proxy server is the bottle neck??? On Tue, Feb 12, 2013 at 1:44 PM, <A.L.M.Buxey@lboro.ac.uk> wrote:

There are many different things you are talking at the same time. You want increase the response time of auth. Is your database indexed? Thanks On Tuesday, February 12, 2013, Muhammad Nadeem wrote:
