Anyway, I think researching import tree of popular library is good startline about optimizing startup time.

I agree -- in this case, you've identified that asyncio is expensive -- good to know.

In the jinja2 case, does it always need asyncio?

Pep8 as side, I think it often makes sense for expensive optional imports to be done only if needed. Perhaps a patch to jinja2 is in order.

CHB

For example, modules like ast and tokenize are imported often than I

thought.

Jinja2 is one of libraries I often use. I'm checking other libraries like requests.

Thanks,
