Performance tweaks for RADIUS and backend authentication systems
13 July 2015 at 2:59pm
Successful deployments of 802.1X (as used in eduroam) mean that large numbers of clients will be using RADIUS authentication methods to get online. Whilst eduroam is just the proxying of RADIUS packets, the system fails if the local authentication service cannot handle the requests sent to it in time (e.g. slow backend authenticator). So this article is a place where RADIUS admins can post tweaks and performance enhancement tips for their chosen platforms. If any sections are blank then that is due to no feedback from the community (crowd sourced document)
