Benchmarks

This page shows how long one server tick takes with many dropped items, with Velox and without it.

Each number is in milliseconds per tick. Lower is better. A server runs 20 ticks per second, so each tick has a budget of 50 ms. If a tick takes less than 50 ms, the server keeps up.

The main results

Situation	Items	Normal game	Velox	Faster by
Resting on the ground, spread out	10,000	57 ms	20 ms	2.9 times
Resting, a medium crowd	50,000	487 ms	71 ms	6.8 times
Resting, packed together	100,000	3,315 ms	171 ms	19.4 times
Resting, one million items	1,000,000	25,495 ms	2,827 ms	9.0 times
Falling from a height	100,000	1,597 ms	235 ms	6.8 times
Sliding on ice	50,000	1,022 ms	99 ms	10.3 times

What the numbers mean

• Velox is between 3 and 19 times faster. The more crowded the items are, the bigger the gain.
• Velox keeps about 25,000 to 35,000 items inside a 50 ms tick. The normal game keeps about 5,000 to 9,000 items when they are spread out, and fewer than 3,000 when they are piled up.
• Velox does not make a million items playable. A million items take 2.8 seconds per tick with Velox, and 25 seconds without it.

How the tests were made

• Measured on 2026-10-22, with Velox 0.1.0 and Celeris 0.3.0.
• Minecraft 1.21.1 with NeoForge and Java 21.
• A shared 4 core cloud machine. Read differences under about 20 percent as a tie.
• A dedicated server on a flat world. No players were connected. Other mods were not part of the test.
• For these runs, maxItemsPerLevel was 1,048,576 and windowSections was 96. The defaults are 32,768 and 48.

The full tables and the method are in docs/benchmarks.md in the repository.
