It depends on the setup and how many users you have put behind it.
-
there are 2240 users behind Captive Portal.
and i use pfSense 2.0.3-RELEASE (amd64) on Sun x4150 machine… (2 x Intel Xenon E540 CPU, 16 GB RAM, 4 Gigabit ethernets, 5x146 GB SAS Disk RAID5)
captive portal settings are as below
freeradius authentication, disable mac filtering, disable conccurrent logins, hard timeout 7 daysany idea?

I would recommend to move to 2.1 since there are quite a few optimizations that you will benefit from.

thanks..I'm planning to move to 2.1 whenever 2.1 becomes stable…

For 2.0.3 features is quite stable.
Only some IPv6 related issues are the ones being looked after.
