Pppoe and performance vs hardware

[benoit]

hi,
do somebody have some performances figures to share ?
I'm looking for a box that should support around 500 pppoe users and therefore that should support around 100mbits of traffic permanently.

Do somebody have any idea of the hardware i need to accomplish this ?

we run about 50 users per box at the moment with cpu at about 30%
and memory at 30% this is running pfsense with ospf pf and a couple of
other things. with about 2-4 mb useage.

266 mhz wrap baord with 128 mb ram.

our scale point is about 1500 users with 2 gb ram and dual 2.0ghz opteron.
i dont know what it really will need till we get there though.

266*0.30 = 79.50 for each 50 users
79.50 / 50 = 1.6 for each user

1.6 * 1500 = 2396mhz which should allow for lots of overhead there.

ram

128 * 0.30= 38.4 for each 50 users

38.4 / 50  =0.78 for each user

0.78 * 1500 = 1152mb for 1500 users

this reconciles with what i have been told before

1 gb for each 1000 users and 2 ghz

hope it helps

Nice Aldo, keep us updated how these values scale when you have the real 1500 user setup  ;D
