Very light. World size drives memory, not CPU.

The entire world is held in memory, so a large world costs several times a small one before anyone connects. Thirty-two players on a small world is cheaper than four on a large one. Large content mods add both world complexity and new entities, raising the floor further.
The mistake to avoid
Picking the largest world by default. Choose the world size for the playthrough you want rather than for the maximum, because it is the single biggest lever on both memory and world-generation time.
