I know it's off-topic for this list, but I imagine someone on here
might have some ideas :
At work we have a 2mpbs line and I have a box doing traffic shaping
('wondershaper using htb) and accounting (254 addresses, in and out)
as a bridge (ie we simply stuck it between the network and the ISP
provided router). This box is a 1GHz Celeron.
We are upgrading to a 6mpbs line, and have the opportunity to run the
gateway box as a router instead of a bridge. I built the new box with
a 1GHz Pentium III.
However, the new box cannot route packets at full line speed - even
with accounting and traffic shaping disabled. We tried it with a
server that's 'between jobs' at the moment, a 2GHz, dual quad-core
Intel something - that can route the packets and count them, but
still can't handle the traffic shaping.
I have a couple of questions :
1) Does anyone know if there is any significant different in
performance between routing and bridging packets in Linux ? Ie, if I
reconfigured this new box as a bridge and sourced a different box to
do the routing, would it be likely to handle the traffic better ?
2) Am I right in thinking that routing/accounting/shaping lots of
packets won't use multiple cores effectively ? So we'd be better of
with a faster single core machine ? We have a quote for a new box
(2GHz Xeon) but we don't want to shell out and find it still can't
cope.
ANy ideas greatfully received.
