Here is a very good thread from @jeff that lists also VPN performanc for a lot of devices:

Comparative Throughput Testing Including NAT, SQM, WireGuard, and OpenVPN

Overview While there's been a lot of individuals testing various routers, the question still always seems to come up, "What can I expect from Router X?" I won't say that my testing is going to definitively answer those questions, but at least it should be a self-consistent data set. To be very clear, this is a benchmark. Like most benchmarks, the performance you get in your own environment may be different. If you have a craptastic ISP, a lossy ISP connection, a flakey cable, hosts pummeling y…

I think i'll try openvpn then, i tried l2tp but i couldn't make it running
