Re: Load testing tool recommendation
Hmm.. I *am* referencing the radius server with FQDN ... Lemme flip that switch and see what I get to play with ... Good catch .. It's letting me ship some more packets through per second.. no final figures yet, but starting to hit 5k pkts/sec, though the radius server is still not sweating nearly as much as I want it to (sitting between 12-15% CPU, and client system is maxing itself out trying to keep up, and the clients is a bigger machine than the server) ... //anders ----- Original Message ----- From: "A L M Buxey" <A.L.M.Buxey@lboro.ac.uk> To: "FreeRadius users mailing list" <freeradius-users@lists.freeradius.org> Sent: Tuesday, May 13, 2008 2:55:56 PM GMT +00:00 GMT Britain, Ireland, Portugal Subject: Re: Load testing tool recommendation Hi,
Nope, no wireless involved.

:-) ah. joys. there might be issues with networking stack dealing with those numbers of new connections per sec- plenty of online resources that will tweak those aspects of the stack but you may need to launch several client threads to get this ramping up - dont forget, the server itself is multithreaded and generally its 3rd party auth bits (mysql, postgres, AD etc) that will be the deciding factor. alan
Curious... It's a fairly beefy Linux box with GigE NIC .. Hmm.. Time to dig into sysctl, and playing with the forking script, as the speedup I'd need would be client side it seems to me. Server has taken what I've thrown at it so far, without batting an eyelid.. //anders ----- Original Message ----- From: "A L M Buxey" <A.L.M.Buxey@lboro.ac.uk> To: "FreeRadius users mailing list" <freeradius-users@lists.freeradius.org> Sent: Tuesday, May 13, 2008 5:28:00 PM GMT +00:00 GMT Britain, Ireland, Portugal Subject: Re: Load testing tool recommendation Hi,

What kind of NIC? There are some (cheap) cards which are using the CPU pretty heavily. cheers, Jens -- sage@guug Berlin: http://www.guug.de/lokal/berlin/index.html http://www.openbc.com/go/invita/4269460
