Can barely reach 2 Gbps in download

Hello @ippj - welcome to the IPFire community!

I am curious - what is the announcement? Can you point me to the link you saw?

The issue above is not one I can assist with. I have seen other discussions with similar issues. I’ll look around…

EDIT: like this:

Slow Speed Red <-> Green

It is not the cpu that is the problem but the network controller chip on your motherboard. It is only using one core of your cpu. On the APU4 the network controller chip distributes any network traffic across multiple up to all 4 cores of the cpu as required.

D525 for 1GbE Internet (IRQ CPU hogging)

Update: The built-in irq balancer is poor. It puts all irq load from both active nics onto a single thread. Once I manually tuned SMP affinity to manually assign each NIC IRQ to a different core, I got an instant 50% improvement in throughput (to 750 Mbits). http://www.alexonlinux.com/smp-affinity-and-proper-interrupt-handling-in-linux

IPFire slow when download > 1GB files

if you are using PPPoE you may want to look at receive packet steering. It does not save a slow cpu, but it helps, if all cores were not used. In my testing atom C2758 with PPPoE on a gigabit connection went from 200mbit to about 600mbit including IPS. you can check with: “cat /sys/class/net/ppp0/queues/rx-0/rps_cpus” response on 8 thread cpu will be something like: 0f this is a bitmask for cpu threads, on 8 thread cpu you want to set it to ff with: “echo ff > /sys/class/net/ppp0/queues/rx…

Minimum CPU Performance for a Gigabit WAN Link via PPPoE?

Hi, You may need to tune the network stack and buffers. Check the interrupts on the network card. Are they high? Check this link out:- BR Joe.

with the above I searched for the word “slow”:
