What's new

1.0.0 - first release

  • Per-chunk tick profiling: block entities, entities, scheduled block/fluid ticks, random ticks - real nanosecond timing, not an estimate
  • /lagfinder top with ms/tick, % of tick, most expensive block-entity/mob types, nearest player and a clickable [tp]
  • /lagfinder show in-world glowing markers (vanilla block_display - visible on unmodified clients), /lagfinder hide
  • /lagfinder export self-contained HTML heatmap + table
  • /lagmap works as an alias
  • Server-side only, no dependencies, zero overhead while not sampling
