+# ASV benchmarks
+
+These benchmarks measure `codecarbon` performance across git commits.
+
+Run a local smoke check:
+
+```bash
+uvx asv --config benchmarks/asv.conf.json run --quick --show-stderr
+```
+
+
+Run across releases:
+
+```bash
+# Get the commits of the releases
+./benchmarks/get_release_hashes.sh
+# Run only against those commits
+uvx asv --config benchmarks/asv.conf.json run HASHFILE:release_hashes.txt --show-stderr
+```
+
+Then when you see a big jump between releases, go and run the intermediate commits to see the diff:
+
+```bash
+# Imagine the jump is between 3.2.1 and 3.2.2
+uvx asv --config benchmarks/asv.conf.json run v3.2.1..v3.2.2 --show-stderr
+```
+
+Build and preview the report:
+
+```bash
+uvx asv --config benchmarks/asv.conf.json publish
+uvx asv --config benchmarks/asv.conf.json preview
+```
+
+Generated ASV environments, results, and HTML are written under `benchmarks/`.
