re: rates. There is a big difference when the cpu supports AES-NI because the hw offloads a lot of the encryption work which would otherwise been done with many instructions using a software library. The i5-5250 (2015) is just a hair slower than the i7-4500u (2013). You can see here the i7-4500u can do 299Mbps. https://forum.pfsense.org/index.php?topic=115673.0. I've got 225Mbps service and I'd like to know if the i5-5250 could keep up too.
