TNTmark
by ogFIRE08
TNTmark is a Fabric utility that benchmarks a CPU by igniting escalating waves of TNT in a world and recording how the server ticks hold up.
What it does
Each run places TNT that is ignited about 250 blocks up, where the blocks float in the air and the explosions take blast damage. The wave count doubles each round, and the run ends once the measured TPS falls below 15. A score is then printed in chat, and the result is written to disk. A run can be cancelled early with the stop command.
The mod is client-side only, so players install it alone and servers do not need it. Single-player always works, and on a multiplayer server the operator needs OP level 2. Fabric API is required as a dependency. Builds exist for 26.1 and 26.2, with 1.1.0 for 26.2 as the latest file, and the code is released under the MIT License but is not open source.
Key features
Escalating TNT waves
Each wave doubles the TNT count, which steadily increases the load on the processor until the run finishes.
TPS measurement under load
The mod records ticks per second during each wave, showing how the system holds up as the explosions grow.
Repeated runs per wave
Several runs are made for each wave, so the result rests on more than one measurement.
Automatic game rule restore
Game rules are adjusted for the benchmark and restored afterwards, so the world is left clean after a run.
Timestamped result files
Each run is saved as one timestamped file inside the tntmark-results folder in the game directory, which makes comparison over time simple.

Use cases
Comparing hardware or setups
Players can run the same benchmark on different machines and compare the printed scores against each other.
Tracking changes over time
The timestamped files let a player see how the same setup performs after updates or hardware changes.
Who it’s for: Players who want to measure their CPU under load, and server owners who want a repeatable test on a single machine.

A Fabric mod for Minecraft 26.x that benchmarks your CPU using TNT explosions. It spawns increasing waves of TNT, measures your TPS under load, and calculates a score — so you can compare your system's performance against others. The benchmark runs on its own from there: every wave doubles the TNT count until your…
