Benchmarks

Here, common Minecraft servers are compared against Pumpkin.

Caution

This comparison is unfair. Pumpkin currently has far fewer features than other servers, which might suggest it uses fewer resources. It's also important to consider that other servers have had years for optimization. Vanilla forks, which don’t need to rewrite the entire vanilla logic, can focus exclusively on optimizations.

Note

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. All servers used their own terrain generation, no world was pre-loaded.

Important

CPU Max is usually higher with one player as the initial chunks are being loaded.
