Description

There's a lot to gain from speeding up pip's startup time.

For one, pip takes around 600ms to just print the completion text, which is laggy. (as mentioned in #4755). Further, faster startup time might help with the test-suite situation too.

Contributor guide

Research direction
Profile pip's startup process using cProfile or py spy to identify slow modules. Focus on imports of optional dependencies and command parsing. Consider lazy loading or delaying imports.
