Description
setuptools version

Python version

OS
Windows

No response
Description
Importing setuptools is slow and takes nearly half a second. This imposes significant performance impact on CLI applications (https://github.com/Azure/azure-cli/issues/23177).
Expected behavior
Importing setuptools should be fast.
How to Reproduce
import setuptools
Output
python -X importtime -c "import setuptools" 2>perf.log ; python -m tuna .\perf.log
Without setuptools, importing distutils is pretty fast:
python -X importtime -c "import distutils" 2>perf.log ; python -m tuna .\perf.log

Research direction
Start by reproducing the Windows case with python -X importtime -c "import setuptools" and inspect the resulting perf.log with python -m tuna. The issue names no source files or tests; done means identifying and reducing the import-time overhead while preserving the existing setuptools import behavior.
