RB3011UiAS-RM and IPsec

Hello.
I want to replace my slow RB2011UiAS-2HnD-IN with RB3011UiAS-RM. I need to improve VPN (L2TP/IPsec with AES-256). My current give 16 mbit/s DL and 19 mbit/s UL. What speed I can get on RB3011UiAS-RM? It support Hardware Acceleration or not?
I want to buy separate Wi-Fi access point. What you can recommend? I think about RB952Ui-5ac2nD-TC. I will able to connect they together, and power Wi-Fi over PoE?
