Are 4x3.5GHz CPU Am4 and 32gb RAM good for a Minecraft server?
Clear. The ram is great.
How many players can do that
With plugins per player approx. 50 - 120MB, per large plugin (BSP: mini games like BedWars) another 200MB. 1 Spigot server can be calculated with 150MB. I'm talking about the Ram.
Yes that is very good. There should already be ~ 200 players on it.
