Benchmarks

Here, I compare common Minecraft servers against Pumpkin.

Is this comparison fair?. Not really. While you could say Pumpkin currently has way fewer features than other Servers which should use less resources, You should also consider that other Servers had already Years for Optimizations, Especially Vanilla forks, which don't have to go through the pain of rewriting the entire vanilla logic, are free to focus 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 ITS OWN TERRAIN GENERATION, NO WORLD WAS PRE-LOADED
