The verdict

Nothing crossed a threshold

No measurement of this run points to a defect. That describes this run under this load, not every load.

Weakest test: Mob AI, 10.8 TPS on average. The 15 other tests hold at least 19.76 TPS.

Settings your measurements justify

Each setting below is triggered by a measurement from this report, and names the test to replay to find out whether it helped.

Spigotspigot.yml

Shrink the monster activation range

world-settings.default.entity-activation-range.monsters: 24

Measured : mobAI.mspt.avg 100.4 ms (threshold 35.0 ms)

Mob AI costs more per tick than the budget allows. The activation range decides how far from a player a monster keeps thinking; shrinking it puts distant ones to sleep without removing them.

Test to replay : mobAI

Bukkitbukkit.yml

Lower the monster spawn limit

spawn-limits.monsters: 50

Currently : 70

Measured : mobAI.mspt.avg 100.4 ms (threshold 50.0 ms)

Mob AI is past the critical cost per tick, where shrinking the activation range is no longer enough. The spawn limit caps how many monsters exist per player at all, which is the only setting here that reduces the work rather than deferring it.

Test to replay : mobAI

These settings trade a little gameplay fidelity for tick budget. Apply one at a time and replay the named test: the effect stays a hypothesis until you have measured it.

Replace server.jar with your server's jar. Paste the line where your server is started: the start-up parameters (or JVM arguments) of your hosting panel, or your start.sh / start.bat. Only the corrections above differ from your current line.

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.

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

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.

Run conditions

What the plugin saw of the host during the benchmark, and what the site concludes from it. The plugin reports facts; the verdicts and their thresholds are the site's, the same ones the diagnosis and the API use.

The reference computation timed during the run kept its pace, and the hypervisor took no significant CPU time.

A CPU quota, a reduced CPU set or a memory limit applies to the server.
