I have two communities in place, and they are starting to “grow”.

Doubt: What is the component that is most impacted (and will have to be increased faster) with the growth of communities? Memory, CPUs or disk?

Which one is most determinant for performance?

CPU and memory, with a priority on memory. As long as the disks are SSDs they are unlikely to be a bottleneck.
