I had to upgrade my pfsense hardware when I got fiber several years ago, which was in a similar situation as yours. The CPU just couldn't handle the connection table.
I use Roman deities. My recent Beelink purchase received the name Mellona. I thought it was fitting. Others have no relevance, just random, like Pluto, Juno, Jupiter, Neptune... double fun for them being space objects as well.
If the grass looks greener on the other side it's probably being well fertilized.
