Benchmarks
Here, I compare common Minecraft servers against Pumpkin.
Is this comparison fair? Not really. While Pumpkin currently has far fewer features than other servers, which might suggest it uses fewer resources, it's important to consider that other servers have had years for optimization. Especially vanilla forks, which don’t need to rewrite the entire vanilla logic, can focus exclusively on optimizations.
ALL TESTS HAVE BEEN RAN MULTIPLE TIMES TO GUARANTEE CONSISTENT RESULTS
ALL PLAYERS DID NOT MOVE WHEN SPAWNING, ONLY THE INITIAL 8 CHUNKS WERE LOADED, THAT'S ALSO THE REASON CPU MAX IS USUALLY HIGH ON THE FIRST PLAYER ALL SERVERS USED THEIR OWN TERRAIN GENERATION, NO WORLD WAS PRE-LOADED
