Hardware and Performance / Re: PC Engines APU2 1Gbit traffic not achievable
« on: August 07, 2018, 07:55:27 pm »Hello pylox, all
just to be clear: I am testing through plain IP+NAT connection (PPPoE was mentioned as a possible bottleneck, but not tested YET), and that simple test setup has approx. only 40-50% of the max. possible throughput. If I add PPPoE, it will be even slower. That's the point of this thread, trying to find at least 1 credible person who is currently using APU2 with Opnsense, and he/she confirms their speed can reach 85-90% of gigabit (at least). Even if using over PPPoE!
Then the next round will be to see, what needs to be fine-tuned to have the same perf at my ISP.

Hi ricsip,
this ist very hard to find. Unfornatunatly i did not have a test setup with a APU2 (and not much time).
But you can try different things:
1. Change this tunables and measure...
vm.pmap.pti="0" #(disable meltdown patch - this is an AMD processor)
hw.ibrs_disable="1" #(disable spectre patch temporarily)
2. Try to disable igb flow control for each interface and measure
hw.igb.<x>.fc=0 #(x = number of interface)
3. Change the network interface interrupt rate and measure
hw.igb.max_interrupt_rate="16000" #(start with 16000, can increased up to 64000)
4. Disable Energy Efficiency for each interface an measure
dev.igb.<x>.eee_disabled="1" #(x = number of interface)
Should be enough for the first time...;-)
