Intel D2500CCE Gigabit throughput?
-
Hey Gang,
Is anyone getting gigabit throughput on their Intel D2500CCE (dual core Atom @ 1.8ghz)? I can't seem to get more than 750mbit before topping out the CPU, ~half consumed by interrupts from the nics. I've tried enabling polling, which lowered CPU usage but dropped throughput to ~350mbit. I've attempted to disable MSIX and MSI without much change. I'm on 2.3.1-P5 amd64.The pfSense store sells the SG-2440 that claims gigabit throughput on a dual core 1.7ghz Atom.
Anyone getting gigabit throughput with this setup?

This image will be pre-tuned and in normal over the PPPoE you will not be able to get really 1 GBit/s routed
from what I was seeing and reading here in that forum.Anyone getting gigabit throughput with this setup?
In some cases a Jetway NF9HG-2930 without PPPoE (FTTH) is able to reach 1 GBit/s
and in other cases a Supermicro C2758 isn´t able to reach 1 GBit/s at the WAN port. -

Those are very very very different Atoms. The D2500 is what we call an in-order execution core and the Rangeley Atom is an Out-of-order execution core.
OoOE is much faster than IOE but requires more transistors (uses more power with the same manufacturing process).
It was only years after the first Atom was launched that the technology allowed them to develop OoOE Atoms without breaking the power envelope Intel wanted for Atoms. -
Cheers, folks. I appreciate the response.
Sounds like I need beefier hardware for 1gbit nat. Off to migrate to Hyper-V I go!
Thanks!
