  Only during parsing.

  Even in decent OSes it is a lot of overhead compared to eg. having
the macro in memory. Or even in the same file.

  You can test this in practice: Make a loop which calls a macro which
is located in another file and measure how long it takes. Then move the
macro to the current file (where the loop is) and measure again. You will
probably get a significant increase in speed.
