pfSense slow site-to-site VPN

You'd probably be better off using VyOS to do routing. Pfsense really does seem like a kludge after getting to know VyOS.
NTG Lab has a massive quad core Xeon, 12GB RAM, VyOS router heading to the LA Colocation America facility right now

Thanks everyone for all your suggestions, really appreciate that. Getting back a little late here, totally forgot that my wife planned a small trip for today
@IT-ADMIN: Thanks, already on my todo-list. Just had no machine at hand. I know about issues with pfSense running virtual, but as I said, performance is great when plain traffic gets routed over virtual and / or physical NICs. But you are right, should take virtualization out of the equation.
@Danp: Agree.
@travisdh1: Interessting, didn't thought about running OpenVPN standalone outside of pfSense. pfSense is known to be a bit... picky when it comes to OpenVPN. BTW: Im not a big fan of Vyatta. pfSense is running on my sites for nearly 10 years now. Would rather like to solve the problem
@scottalanmiller: Single core load measured over 5 mins outside of business hours.
Will test with a physical pfSense on some Intel NUC maybe. If that does not work, I could still do some tests with a standalone OpenVPN on some Linux host. Will report back later.
-
okay, single core that's not too bad. I'd still check the load numbers (uptime will give you this quickly) and see if there is some wait state catching you.
-
@scottalanmiller good point, thanks

before continue reading your issue, i want to tell you that pfsense will not play well in virtual environment, in their official website too many people complaining about slow connection when installing pfsense in virtual environment,
That used to be the case, newest versions are fine.

Why Open VPN for site to Site over IPSEC? OpenVPN is normally much slower..
OpenVPN was more made for easy configuration.
-
Also have you considered TINC full mesh on Pfsense, I have used it in the past when I worked at smaller companies.

No preference for OpenVPN, tried both, IPsec being just 1MB/s faster. Oddly, latency is still great while throughput is low. Both lines are sync 1GB/s, just some fiber and roughly 4 km / 2.5 miles in between. Next to no reflections on the fibre.
Async lines are a known problem especially in OpenVPN, but that shouldn't be the case
-
@Jason Not yet. Problem is, there's some confidential data going over that wire. Sure, already encrypted on OSI-7, but I don't feel comfortable using a solution in this context I don't know. Would rather like to stick to IPsec (preferred) or OpenVPN.

Does it have built in PV drivers for most platforms? Which ones does it support well?

Specifically in CPU usage.

What's your protocol set to? TCP or UDP?

@marcinozga Thanks, but already tried net.inet.ip.fastforwarding in all combinations with TCP and UDP.
