From what I understand from reading up on the forum, Rangeley pushes accelerated VPN into the hundreds of megabits already.
But this is also hard pending on which model is soldered on the board.
At this days the Rangeley SoC is really rocking if the OS on it is using
the AES-NI instructions and for sure for vpn tasks.
QuickAssist would take this into the tens of gigabits, but I really don't foresee to have anything more than a 1Gbps fiber connection for the next 10 years or so.
But this is only the half of the truth about Intel QuickAssist, it would be also speeding up
tasks that are profit from that, likes Snort, Suricata, OpenDPI and others.
That's why I think Rangeley is too high end for my needs, and that personally makes it hard to justify the price for it.
For sure that is a very new platform and many Vendors are bringing out of them now
and there fore the prices are often very high at the beginning.
I'm moving to 500/500 fiber this summer, and want to take full advantage of it with a new pfSense setup! I'm aware that many 'lower' end systems are well capable of routing 500Mbps, but I'm a heavy VPN user (both IPsec as OpenVPN) and thus require a AES-NI
For sure I would have a look for something between 2 core / 2 GB RAM and 8 core / 8 GB RAM
likes 4 core / 4 GB would fitting your needs at best as I see it right. ;)
capable system in order to maximize VPN bandwith.
Installing this card and you will be happy too, but the QuickAssist and AES-NI
I would prefer at this days and the card is also able to install on top, for sure! ;D
