I did some more tests and it seems with SQM at 500 megabit/s I start to
lose packets at around 250-300k PPS. At these speeds, the rrul_be test is
"only" 85k PPS at 500 megabit/s bidirectional with large packets.
Also, I have an Edgerouter ER-5, but as soon as it does CPU based
forwarding it's really weak, easily under 100 megabit/s even with large
packets. OpenVPN without encryption is less than 20 megabit/s.
Btw, the WRT1200AC is now becoming more widely available and it's 150 EUR
incl 25% VAT and shipping here in Sweden now.
Btw, I tried WNDR3800 setting it to 100/100 SQM. It seems to max out
around 25-30k PPS, but the difference is that when the CPU is full, it
seems to delay/ECN-mark packets because there are no packets lost. When
the WRT1200AC runs out of CPU it starts dropping packets. I always have 0
packets lost with the WNDR3800 when doing iperf3 testing. I found this
difference interesting, wonder where in the forwarding path the WRT1200AC
