PC Engines APU2 OpenVPN performance

[molotch]

I recently bought an APU2 board hoping I could reach OpenVPN speeds close to 100 Mbps (using AES-GCM cipher) since that seems to be achievable with pfSense according to this article.

Anyone here using the APU2 board that managed to get close to 100 Mbit in performance with OpenVPN or have any hints on what I could try to get closer? I am using an AES-GCM cipher and have tried increasing the send and receive buffers. No luck, I max out at about 60 Mbps up and 50 Mbps down.

Seems strange that pfSense should be that much faster. If I connect to the provider using OpenVPN on my computer I max out my connection of 150 Mbps both up and down. I test performance with the homepage www.bredbandskollen.se.

Is your Power Savings set to mode Maximum for highest performance? I found that helped sometimes on APU2.

System>Settings>Miscellaneous>Power Savings
Use PowerD: checked on
Modes set to: Maximum

May need reboot, maybe not. I can't remember I no longer user my APU2.
