Not really. Just perfoming a lot more operations than were necessary.
With spacing = 10, pixels were only plotted every 10th X coordinate and
every 10th Y coordinate. Ninety-nine out of 100 pixels were calculated
but not drawn. Coordinates were only drawn if they were multiples of 10.

Try taking out the MOD lines and see what difference it makes. (For the
best effect, leave the rest of the function as you originally posted it.)

Ooh, does that mean we get to go hunting that snipe?
