### Spark support - Works alongside Spark when it's installed. Pulls its 5s / 10s / 1m / 5m / 15m TPS, MSPT median and p95, server CPU use and per-collector GC stats into the report - Spark is optional, nothing changes if you don't have it - Can be turned off with `use-spark: false` in the config ### More accurate results - GC overhead is now measured since the last check instead of since boot, so servers with long uptime score correctly - Current TPS uses Spark's 10 second window when available instead of a 1 minute average - Shows how much CPU the server itself uses next to the whole machine, and flags when something else on the box is hogging it - Player capacity now accounts for real tick headroom when players are online - Disk read and write speeds use the real elapsed sample time ### New commands - `/benchmark tps` - instant TPS, MSPT, heap, players and entities with no sampling delay - `/benchmark compare` - diffs your last two results, green for better and red for worse - `/benchmark monitor` - shows the last background check ### Background monitor - Optional timer that runs a benchmark every few minutes, logs a one line summary and warns staff with `serverbenchmark.alerts` when issues show up - Off by default, enable under `monitor:` in `config.yml` ### Report additions - TPS trend row (1m / 5m / 15m) - Spark section with MSPT percentiles and CPU windows - Per-world chunk, entity and player breakdown - GC collector rows with average pause and frequency - Data source line so you know where the numbers came from - New issues and tips for recent lag, long GC pauses, small heaps, empty worlds with chunks loaded and main thread bound servers - JSON exports include worlds, Spark data and GC details

- Fresh new look for the benchmark report, way easier to read - Default run is now a short summary, use `/benchmark detailed` for everything - Disk speeds are now measured live (real MB/s instead of totals since boot) - Shows MSPT next to TPS on Paper servers - More accurate scores, especially on servers with long uptime - `/benchmark export` now works and saves a JSON file - Added `/benchmark reload` - Command now works from console too - Fixed crashes on some VPS hosts - Performance and stability improvements
