Sounds like the APU2 is maxed out on CPU. If you have not already, try installing the latest BIOS and make sure the "Core Performance Boost" setting is enabled, which will increase the CPU clock under some conditions: https://pcengines.github.io/apu2-documentation/apu_CPU_boost/ When tuning my APU2 I also found that disabling PCI power management (2. setup -> y. PCIe power management features) also increased throughput. With these two settings and jumbo packets it is able to do close to a gigabit (just routing and PF, no IPSEC, though). -- Darren Tucker (dtucker at dtucker.net) GPG key 11EAA6FA / A86E 3E07 5B19 5880 E860 37F4 9357 ECEF 11EA A6FA Good judgement comes with experience. Unfortunately, the experience usually comes from bad judgement.
