Guys,

I'm trying to setup VPN client on my router to tunnel all internet connection through it. Specs:

Router: NetGear R6400 v2
CPU: Broadcom BCM4708C0 (1 GHz, 2 cores)

Configuration:




On my desktop, i'm reaching around 100mb/s.
While running on router i get only around 30 mb/s.

During the speedtest load, the router's cpu is only loaded at 25% maximum (0.25). So it looks like the cpu is not the problem.



What might be the reason for such degradated performance?
Can i do anything to improve it?

[egc]

I have an R6400v2 running OpenVPN to PIA it will get me max 35Mb/s when it is not doing anything else and with AES 128.

If you want faster VPN speed you need a faster router like an R7800.

I saw an interesting paper by Jason Donenfeld (Wireguard) and one of the reasons it is much faster is that everything is done in kernel space.
So the switching between user and kernel space looks like one of the main culprits of slow performance of OpenVPN on these simple ARM cores
