Hi,
When I try an authentication request, it seems too slow:
yep
I have only 3 clients and in radius.log I see a lot of
only 3 clients could be a small issue - each client can only have a limited number of RADIUS connections. the main issue is number of users - and amount of accounting transactions being undertaken due to them. authentication isnt the headache that accounting is. so, 1) have you tweaked any of the SQL settings for performance in FreeRADIUS eg have more connections number of connections per client etc? 2) MyISAM or InnoDB if using MySQL ? former is default..and sucks. use InooDB if using MySQL. 3) do you need realtime accounting or can you have a slight delay of seconds? if the latter, then consider using the buffered-sql virtual server 4) upgrade alan
