Performance and Diagnostics

The project currently centers around three main performance tools:

1. LayoutCache to reduce unnecessary recalculation
2. UnivisLayoutProfilingPlugin to measure runtime cost and display the overlay
3. ./scripts/run_perf_baselines.sh for repeatable CLI baseline runs

What To Watch

• dirty ratio and recalculated node count
• pass_up and pass_down timing
• material sync timing
• newly allocated versus reused materials
• baseline drift in the solver and runtime benchmark scenarios
