No, you've got that backwards.  You want _more_ blank lines. A blank
line takes zero time to run, but it still counts as a line in your
lines/second stats.

A loop containing 1 line of code will execute in the same abount of
time as that loop with 1 line of code and 99 blanks lines.

The latter loop is running at 100 times as many lines/second as the
former.   That's _got_ to be better.
