Hello all,

as I am planning to buy new hardware for pfSense, I was wondering if it is worthy to buy a CPU that supports "AES new instructions", i.e. hardware-support for AES encyption.

Would pfSense use this CPU instructions so to hardware-encrypt/decrypt all VPN traffic (openVPN)?
Woud pfSense benefit from this in any other way, too?

The motherboards that I want to buy unfortunately support AES-NI only with Xeons that currently start from approx 170 €. If I would take a CPU without AES-IN, I could go with a dual-Pentium for 40€. What impact would you expect from AES-IN, in regards to the fact tht I will be having traffic from VPN secured WLAN with approx 300-450 Mpbs and VPN to/from the internet, 1-2 users at a time max. Do you think the AES-IN would be worthy the price premium of the Xeon for my case, e.g. because it would reduce VPN latency, etc., or is it just a pure waste of money in my case?

Best regards
Thinker Rix
