+## Benchmarks
+
+YASL includes a dedicated performance microbenchmark target (`yasl-benchmark`) evaluating CPU efficiency, memory footprint, cache line pressure, and data structure operations across core hot paths (surface lookups, input queue expansions, ring buffer throughput, timer arm/disarm cycles, and multi-output refresh rate scans):

+```sh
+# Run via meson test runner
+meson test -C build --benchmark --verbose
+
+# Or invoke the executable directly
+ninja -C build tests/yasl-benchmark
+./build/tests/yasl-benchmark
+```
