[LARTC] cpu power needed for shaping

[Igor Krneta]

Hello,
My company recently upgraded our internet connection and I need to set 
up shaping. I was wondering , what are the CPU and RAM requirements for 
shaping 768/768 DSL line ?
I have a few old P III's (450 MHz, 256 RAM) and some VIA Eden (533 MHz, 
512 RAM) boxes lying around. Which one would be most appropriate ?

That box would be a shaping only box, and all internet traffic would go 
through it.

Not much. I help take care of a P1-200 with 96MB RAM that does
firewalling, NAT, shaping, and load balancing for a T1 and a 6000/600
ADSL line. It never comes close to having to work hard.

Use whichever one you expect to be stable -- you don't want to have to
deal with crashes. Otherwise, I would use the faster machine just
because it'll be quicker to set up and administrate.

It all depends on how complicated you want your shaping setup to be and 
how many
clients you have to serve. For example, in my home network with 5 client
machines (and something like 10 classes / 5 filters per client), the old PII
machine with 128MB of RAM I was using for this task was 95% idle all of the
time...

If you have thousands of classes and just as many filters, it probably 
would be
different, though.

I think it's quite safe to say that in a normal setup any of these should be
more than sufficient.
