Any vRouter should be able to do this though. All you need for any IPSEC solution is enough offloaded processing power to handle the chosen encryption level.
Yeah, this is 100% about selecting the CPU, nothing else.
That's not entirely true. The problem with high speed I/O is that the kernel eventually becomes a bottleneck. So to get the performance that the CPU is truly capable of you have to basically bypass the kernel.
That's why routers that are using DPDK can get much higher performance.

Just to show how much DPDK can improve things when you have lots of packets and fast interfaces. This is a performance tests using 4x10GbE.

If that's the case, there should be some "better/more" choices than the ER4?

Your basic choices are....
ER4 is you want cheap, small hardware.
Bigger Ubiquiti if you want the same but even faster.
Whitebox with larger than Ubiquiti scale hardware.There are loads of vendors out there, but you are pretty much replicating these three underlying choices in some way. Small hardware, big hardware, white box. In all cases, IPSec is the choice for the fastest option on the given platform.

Shouldn't the first question be - how big are your pipes?
Then - how much of that will run over IPsec?
And - what features do you need?

That's a reasonable question(s)
- Pipe size: 1x 400/400 (AT&T), 3x 500/500 (Frontier) & 1x 1000/40 (Spectrum). Colo pipe will be adjusted as needed.
- How much over IPsec: as much as I can get!
- Features: mainly Site to Site VPN

Well, you have peak 1900 Mbps in one direction and 940 in the other. But you never get that all the way so 1000/1000 in the colo will likely be more than you need. If it's all going to be IPsec traffic then ER4/ER6 is too small. Do you need HA as well?

HA would be a nice "luxury" to have!
If the ER4/6 is too small, what other choice(s) are available?

- So the fastest reasonable is like 500, since the 1Gb has nothing else to talk to.
- That's never a good way to look at it. I see tons of places do this and then realize that they don't even touch what they hae.
- Is that even a need?

Oh, I assumed that those were all different sites, not all in one. Then yeah, that's a lot of speed.

Way too small. You are talking about some crazy serious stuff here.
First, you need to figure out your pipe aggregation and speed from the other sites. The VPN piece isn't so hard, but combining all of those pipes will be.

So the plan to do BGP routing?

I'm just trying to keep it real simple & take advantage of the available internet speeds!

If you have all of those connections to a single colo (I'm not sure that that is what you were saying, trying to figure that out) then there is no simple answer. It's going to be really complex to try to aggregate them.

On the colo side, he has a possible max of 400 + 500 + 500 + 500 + coax (ignored). That is where 1900 came from, 4 remote sites with solid fiber connections.
Now, there is no individual IPSEC tunnel that needs more than 500. He is not aggregating anything.

As much of the available bandwidth (per site) as I can get, this is definitely hardware constrained by the router used.
