Stressmark

New Features

• Rolling TPS/MSPT windows - Independent tick timing with 10s, 1m, and 5m rolling averages, replacing reliance on vanilla getTickTimesNanos() buffer
• Tick monitor with baseline - Auto-calibrates over 120 ticks during stress tests, reports tick ratio vs baseline for relative performance tracking
• Real-time GC monitoring - Listens to JVM garbage collection events via JMX, tracks Young/Old Gen separately with duration, frequency, and memory freed
• Colored metrics in chat - TPS, MSPT, CPU, memory, and scores are color-coded by severity thresholds (green/yellow/red)
• Unicode memory bar - Visual [████████░░░░░░░░] 67% bar in benchmark and stress test output
• GC section in reports - Both /benchmark detailed and stress test final reports now include GC activity (collection counts, pause times, longest pause)
• Sub-scores exposed - /benchmark detailed shows individual TPS, Memory, CPU, and Stability scores alongside the overall grade
• Bottleneck identification - Player capacity calculator now identifies the limiting factor (TPS, Memory, or CPU)
• Disk metrics - /benchmark detailed includes disk space and I/O stats
• Contextual recommendations - Smart suggestions based on TPS, MSPT, memory, CPU, GC, and disk metrics

Bug Fixes

• Fixed TPS always showing 20.0 during lag - Replaced custom calculateTps() with TpsMetricCollector that correctly reads vanilla tick times, and added MSPT spike detection

Improvements

• Stress test periodic updates now log to console only (reduced ops chat spam)
• Ops are only alerted for significant events: TPS drops >20% or memory usage >80%
• GC events during stress tests are logged to console only
• Stress test final report includes GC activity section and GC-based recommendations
