The answer: it depends. I can only give you an example of ram usage in a particular scenario. In a simple home network (Read: home usage) with about 5-8 devices and all IPS rules enabled for all firewall rules, with TLS inspection on 3 devices, it uses around 4Gb of RAM. This is with most features enabled (app/web/IPS/TLS). Download speeds of 300 Gbps sustainable with no slow down.
As far as CPU, it depends even more.... In my performance history, the CPU usage never hovered above 25% which is very good for what I have, a quad core Xeon (a 2.5GHz variant)
What hardware do you have? What CPU? With a regular household there should be no issue, especially since Android/iOS devices will not be using TLS inspection anyways so you would only be using that for Windows/Linux devices mostly.
Also, with the IPS, which uses most of the CPU, it can be tuned by selecting only the IPS rules that you need, such as a LAN to WAN, or WAN to LAN policy. Ect. I hope this helps.
