One or two extra passes may not even be noticeable. The whole
area of performance is tricky, and to really find out what
affects it the most, you usually need to experiment and measure.

You can, for example, get worse performance by doing everything
in a single pass, if it means using complex functions or deep
function call chains that make life difficult for the garbage
collector and stack management -- not to mention the fact that it
really messes with the readability of your code as well.
