Private Internet Access IPSEC Configuration?

[k1ll3ry0]

Does anyone have any insight as to the configuration of an IPSec VPN tunnel through Private Internet Access? They provide the username and password to the node of your choice and I've heard that it's the way to go to avoid the OpenVPN bottleneck of single-threadedness.

I have recently upgraded to a 1 Gigabit connection and I've been using a Full network routed VPN tunnel using OpenVPN with alias exceptions for Netflix and Amazon Video material. This has been working swimmingly until I upgraded to the 1 Gigabit connection because my OpenVPN connection has been throttled to ~350Mbps because of the single-threaded limitations of the tunnel itself.  Has anyone done such a setup using IPSec instead? I've done quite a bunch of research through the pfSense forum as well as OPNsense and it appears as if I may be biting off more than I can chew. I'm very capable of probably making it work but any information before that could help is appreciated! BTW OPNsense ROCKS...switched from pfSense developmental and I love the stability and how frequently it is updated and supported...Not liking where pfSense is heading in terms of Netgate.
