Performance

Benchmarks vs Paper and Purpur

Here's the numbers to back up our claims. We ran Temper MC, Paper, and Purpur through a series of rigorous benchmarks to compare their performance across various metrics. From startup time to memory usage, TPS under load, and chunk generation speed, see how Temper stacks up against the competition.

19X

Times faster chunk generation

Than paper

<25MB

Memory usage

With 10 online players

25X

TPS under heavy load

15.2 TPS with 500 players vs 0.6 on Paper

0.025s

Startup Time

Without initial chunk generation

TPS Under Player Load

20 TPS = perfect

Startup Time

Seconds to first player-ready state, from an empty dir with only the .jar/.exe and EULA. Lower is better.

Memory Usage @ 100 Players

Heap + off-heap in MB. Lower is better.

Chunk Loading Speed

Chunks generated per second. Higher is better.

CPU Usage @ 100 Players

Average across all cores under load. Lower is better.

Max Stable Player Capacity

Maximum concurrent players before TPS drops below 18. Higher is better.

These benchmarks are very unfair, as Paper and Purpur implement the entire Minecraft server logic in Java, while Temper MC is no-where near feature complete and currently doesn't implement as many features of the Minecraft server as Paper and Purpur, so these numbers should be taken with a grain of salt. However, they do demonstrate the potential of our approach and the significant performance improvements that can be achieved by rethinking how Minecraft servers are built.
Some of the numbers don't look right? Come have a chat in our Discord, it's more than likely that we just haven't remembered to update them in a while. Keep in mind that these benchmarks were taken on a high end machine and your mileage may vary based on your hardware and the specific workload, but we hope they give you a good idea of the performance benefits that Temper MC can offer.
