So, I would like to admit I'm an idiot. My problem was I couldn't get full speed on Wi-Fi. Well, turns out my computer was defaulting to connecting to my 2.4GHz network. When I upped the ram and restarted the pfSense VM, for some reason my computer reconnected to the 5GHz network.
On the 2.4GHz network my WAN tops out at 80-90 Mbps
On the 5 GHz network, the WAN tops out at my rated max of 230 Mbps
So, I didn't actually have a problem... just thought I did and managed to convince myself of it.
