Solved Not sure this is the right forum - Asuswrt-Merlin VPN question.

[htismaqe]

My understanding is that OpenVPN is single-threaded - 1 instance, 1 CPU. My question is this:

If I configure a 2nd VPN server, will it use one of the other 3 CPU cores or will both OpenVPN servers use the same CPU?

I want to split the tunneling load if I can, one because it's cleaner (split tunneling vs. no split tunneling) and because I'd like to get maximum performance as well.

Yes, using a 2nd VPN server, RMerlin firmware already does that for us (uses the next core for the next VPN).

Freaking awesome. I posted another post in the buying advice forum that details my needs a little bit more for what I'm trying to do.

Solved - Need Asus travel router...

I just bought an RV and I need a travel router that can take a USB 4G/5G modem. I know a decent Asus router with RMerlin firmware can do this. My primary need beyond that is decent OpenVPN throughput between this device and my Asus RT-AX88U sitting at my home. I plan to have two server groups...

You can check the processor affinity using a command such as this:

# taskset -cp $(pidof vpnserver1)
pid 2333's current affinity list: 1

Excellent, thanks!
