+# cuda.pathfinder benchmarks
+
+These benchmarks measure filesystem-discovery latency in `cuda.pathfinder`.
+They exercise the in-tree source package and do not require a GPU or CUDA
+Toolkit.
+
+The suite uses temporary directory trees prepared before timing starts. It has
+two levels of coverage:
+
+- `find_sub_dirs.*` isolates the underlying filesystem mechanism with realistic
+  one-root and three-root cases, plus wildcard and cache diagnostics.
+- `public_discovery.*` measures cold-cache calls through the public header,
+  binary, and static-library APIs. Fixtures use real NVIDIA wheel layouts such
+  as `nvidia/cuda_runtime/include` and `nvidia/cuda_nvcc/bin`.
+
+The public cold-cache benchmarks clear pathfinder's process-lifetime caches on
+each iteration. This intentionally models first use in a fresh process; the
+small cache-clear cost is included in the reported time. Three roots represent
+a virtual environment, user site-packages, and system site-packages, with the
+target in the last root to measure the complete search order.
+
+## Usage
+
+Requires pixi. The `source` environment installs `cuda-pathfinder` from this
+checkout and works on Linux and Windows.
+
+```bash
+# List benchmark IDs.
+pixi run -e source bench --list
+
+# Quick functional validation; timings are not meaningful.
+pixi run -e source bench-smoke-test
+
+# Run the full suite and write results-python.json.
+pixi run -e source bench
+
+# Reduce runtime while iterating.
+pixi run -e source bench --min-time 0.1
+```
+
+## Comparing changes
+
+Save results from the base revision and the modified checkout under distinct
+names, then use pyperf's statistical comparison:
+
+```bash
+pixi run -e source bench -o results-before.json
+pixi run -e source bench -o results-after.json
+pixi run -e source -- python -m pyperf compare_to \
+    results-before.json results-after.json --table
+```
+
+For stable results, minimize other system activity and use the same machine,
+Python version, and Pixi environment for both runs. See pyperf's system tuning
+guidance: https://pyperf.readthedocs.io/en/latest/system.html#system
