+"""CodSpeed benchmarks for importing entity components.
+
+Every ``esphome config`` or ``esphome compile`` imports the Python module of
+each component the YAML uses. A component that imports its optional
+integrations (mqtt, web_server, zigbee) at module scope drags their whole
+import chains in for every user, so the cost of a fresh import is what these
+benchmarks pin down.
+
+The core of esphome is imported once up front and stays loaded; each run
+drops only the component modules from ``sys.modules`` and imports the
+component again, so the import machinery and the module bodies of the
+component and everything it pulls in run every time, as they do in a new
+process, while a change to the core moves no number here. The modules and
+registry entries the session had before a case are put back afterwards, so
+later tests keep the objects they already hold.
+
+Skipped when ``pytest-codspeed`` isn't installed so the regular unit-test
+suite keeps working unchanged.
