That is all you really need unless you are looking to have 1000s of people connect to it.
That was mostly the idea, since it'd be an open server, let as many people as I could connect to it.
And besides, if I'm also considering whether I could run 2 at once (public and private), I'm guessing that if it's possible, it'd need quite some resources
Let me reword that a bit 1000s of
simultaneous users.
If you have an SSD + enough RAM say 16GB and a 5th gen or better CPU you can easily do 1000s of transactions a day.
You are going to need a powerhouse to do dozens of transactions per minute however.
And in reality unless you are publishing your own wallet that a lot of people use you are never going to get anywhere near hundreds of transactions per week or even month.
If you take a look at:
https://bitcointalk.org/index.php?topic=5229386I had setup a node that I wanted to make private.
After that I actually made a new one opened it up the the world. I think it processed something like 10 transactions over the weeks I had it up.
Took it down last Friday the 3rd when I was leaving the office. It went online between the 10th and 12th of March.
If you tell people about it and have them specify to connect to it you might get more, but just sitting there not so much.
