For informationActivity outside the bench world

When the run started, players or many entities were present outside the bench world. The server ticks them during the tests, so part of each tick went to that world rather than to the workload measured.

  • players_online = 1 count
  • chunks_loaded_outside_bench = 937 count
  • spawn_chunks_loaded_outside_bench = 0 count
  • entities_outside_bench = 247 count
  • worlds_loaded = 5 count
  • players_online_threshold = 1 count
  • entities_threshold = 1,200 count
For informationCold JVM at the start

The run started on a JVM that had just started, or that had not run a bench since it started: code was still being compiled and the heap still growing. The first run after a restart can differ from the next ones.

  • jvm_uptime_s = 883 s
  • bench_runs_since_start = 0 count
  • threshold_s = 300 s

A finding stays silent rather than attribute a cause without evidence. An absent cause is an answer, not an omission.

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.

Nothing to change: no measurement in this report crosses a threshold where a documented setting would help.

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.

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.

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.
