The PEP8 recommends importing like this:

I got a bit further, and if I'm only using a couple of
functions
from the import, I'll list them in the comment.
If I just plan to use a small subset, I tend to reach for the
from sys import stdout, stderr, exit
sort of syntax. I find it makes my code read a bit more
cleanly than
having to type "sys.stderr.write(...)" everywhere but is still
pretty
readable.

So, there are no advantages or disadvantages when disregarding
readability?
Sure, just as one light is no brighter or dimmer than another when
disregarding luminosity.
As people have said, it improves diffs as well. It flows quicker into
the "from module import things" form (which I oft prefer), too.
When asking these questions, ask yourself "why would it *compile*
differently? It wouldn't. Plus, premature optimisation is the root of
all evil.
1) Write your code
2) If it's slow:
2a) Do you have time? If so:
2b) Is it important to speed up, or is the slowness not worth spending
the hours fixing?
2c) Profile it to see what's actually slow
2d) Realise that the slow part is not what you thought it was
2e) Fix the bit that's slow (and nothing else)
2f) Repeat from 2
3) Write some more code
Joshua, nice work-flow instructions.
