+# Continuous performance benchmarks via CodSpeed (https://codspeed.io).
+# Runs the framework's micro scenarios (M1-M7) and four representative
+# macro scenarios (X1-1, X2-10k, X4, X6) on CodSpeed's bare-metal Macro
+# Runners. The Macro Runners give <1 % variance walltime measurements —
+# substantially more stable than shared GitHub Actions runners, which is
+# what makes per-PR perf-regression gating meaningful here.
+#
+# Free for OSS up to 600 macro-runner minutes/month; one run of the
+# benchmark set takes roughly 5-6 minutes.
+#
+# Triggers:
+#   - push to master: track per-commit perf trend on the dashboard
+#   - pull_request with the `perf-check` label: opt-in per-PR
+#     CodSpeed comments. Maintainers apply the label on PRs whose perf
+#     impact is uncertain; routine PRs don't burn macro-runner budget.
+#   - workflow_dispatch: manual trigger, available always
+#
+# Path filter limits triggers to commits that could plausibly affect
+# performance (py4j Python sources, py4j-java sources, the test
+# requirements file, and this workflow itself). Doc-only commits
+# don't burn macro-runner budget.
+#
+# Prerequisite (not in this PR): install the CodSpeed GitHub App on the
+# py4j organization:
+#   https://github.com/apps/codspeed
+# Until installed, this workflow runs the benchmarks but cannot post
+# results to the dashboard (and ``codspeed-macro`` won't resolve to a
+# runner). Maintainer action; one-time setup.
