[Python-Dev] Python startup time

[Chris Barker]

As long as we are talking anecdotes:

If it could save a person’s life, could you find a way to save ten seconds
off the boot time? If there were five million people using the Mac, and it
took ten seconds extra to turn it on every day, that added up to three
hundred million or so hours per year people would save, which was the
equivalent of at least one hundred lifetimes saved per year.

It really does depend on how/what users are using Python for. In general,
Python has been moving more and more toward a "systems development
language" from a "scripting language". Which may make us think "scripting"
issues like startup time don't matter -- but,. of course, they matter a lot
to those use cases.
