A single set of imports, at the top of each file, is better,
because that's the convention.  "Prefer the standard to the
offbeat."

Which is faster doesn't really matter --which is lucky,
because there's no simple answer to that question anyway.

If you need help improving performance in an actual program,
post some sample code.  Otherwise, relax.  :)
