What matters

Read from the measurements, never estimated
Good to know

Non-default server configuration

Compare with care against a server running default settings.

  • view-distance 18 (default 10)
  • simulation-distance 4 (default 10)
  • spawn-limit.monster 60 (default 70)

Java start-up line

The options this server was started with, checked against its Java version. Corrections fix what is certainly wrong; leads to test are settings to measure, never applied for you.

Nothing to correct: every option is valid for Java 25.

To test

Performance settings to try one at a time, then measure with a benchmark before and after. None of them is applied in the corrected line, and none comes with a promised gain.

to testAikar's G1 settings

Settings documented by PaperMC for Minecraft servers: they size G1's young generation for the game's very high allocation rate and start collections earlier. Initial and maximum heap at the same size, with AlwaysPreTouch, commit the whole heap at start-up: proposed only because that heap already stays under the memory limit.

-Xms13424M -Xmx13424M

No measurement of this run points to it: it stays a lead to measure.

to testGenerational ZGC

A collector with very short pauses for large heaps, at the cost of more CPU and memory. It replaces the current collector: remove the current collector option and its own tuning options, then measure. From Java 23 the generational mode is the default.

-XX:+UseZGC

No measurement of this run points to it: it stays a lead to measure.

source

Re-run and compare

  1. Apply the corrected line where your server starts (panel start-up parameters, start.sh).
  2. Restart the server.
  3. Run a new benchmark: /bench start
  4. Compare the new report with this one.
Open the comparison with this report

This report is the before; add the new report to the comparison once it is in. A single run on each side says little: the gap between two runs of an unchanged server is noise.

Every measurement

Each test in full. Tests in trouble are open; the others fold to their summary line.
