RE: Which NIC is better: fxp or dc?


Hello!

Suppose you have to build a high-performance router with several NICs,
and you have to use a mix of D-Link DFE-570TX (21143, MII, quad port)
served
by dc(4), and several Intel 82558/9/0 adapters served by fxp(4). Router
has to have 2-3 high-speed connections and several ones which lower speed
and packet rate. Which NIC (dc or fxp) would you recommend for high-speed
connections: dc or fxp? Which combo (NIC+driver) is more reliable? Which
gives higher performance (reliability for me is more significant than
performance)? Currently I'm using RELENG_4, but in the future I'll upgrade
to RELENG_6 (when it becomes mature enough), so I'm interested in the
state of affairs in both branches.

we have good performance counters for both of them. for support and
common usage reasons (more users mean more testing) we selected the
fxp cards.
as far as i know, there's currently a fxp panic issue in 6.1-BETA4, but i
don't exactly know the details (maybe this is interesting for you).
however, we're successfully running gateways with 10 physical interfaces
being fxp-controlled.

hope that helps!
