Ever since I set up RADIUS logins, I've noticed if I've been logged in as a local user, as opposed to a RADIUS user, it generates errors in my log on commits. Basically it's stating that the local user can't be authenticated against the RADIUS server, so it falls back to local authentication.
I ended up doing a lot of testing and profiling on my 1.3 installs.
It turns out, that on boot, the root user tries to authenticate every commit against the RADIUS server.
Deleting the system login radius configurations causes a 5-6 minute boot to only takes 90 seconds. Strangely enough, deleting the vpn l2tp and snmp configurations, drop the 90 second boot down to 50 seconds.
