If your system is running slowly, perhaps a process is using too much CPU time and won't let other processes run smoothly. To find out which processes are taking up a lot of CPU time, you can use Apple's Activity Monitor.
The CPU pane shows how processes are affecting CPU (processor) activity:

Experimental but very promising pip replacement that handles package managing as well as virtual environments and Python version management.
uv comes included with uvx, an alias for uv tool run. uvx allos you to install and execute command-line tools on an ephemeral environment.
Note that you don't have to actively install a Python version! uv will automatically fetch the required Python version for your project.
This guide describes how to create a local PyPI mirror for use in isolated networks without internet access. We'll use bandersnatch to dump packages, a web server to serve them, and devpi to enable search functionality.
This is possible using devpi, web server, bandersnatch and volume to store the packages.
