SG-2440 VPN Capacity

I plan to buy a SG-2440 mainly for the ability to use VPN.
I know that the more VPN you have the less throughput you may have by VPN.
My goal is to use 6 OpenVPN and 3 IPSec VPN in the same time (at least at start), and i wonder if the SG-2440 will be able to handle this VPNs together.
I don't need a big throughput, only a few Mbps, but i need them to work flawlessly in the same time.
I don't find any capacity load regarding the pfsens Hardware line (surely because it depend on the perf that you need).
Thanks in advance.
There is some overhead when adding more VPNs but it's more about the total amount of encrypted/decrypted traffic. It's also dependent on what encryption algorithm you are using and what type of traffic you're encrypting so it's hard to give a direct answer here.
Generally IPSec will give higher throughput than OpenVPN so if the load was spread evenly it woukd pass more. You can get a lot higher throughput over IPSec if you're able to use AES-GCM which takes advantage on the AES-NI hardware in the SG-2440.
As a very rough guide I would expect to see at least 100Mbps total VPN throughput (probably more) but it's not clear how that would divide. If each tunnel is only passing a few Mbps then I wouldn't expect any issues.
