PHP code comments parse speed

Question

Does anyone have a solid benchmark about the speed of parsing PHP code comments? Meaning, will excessive comments increase the time to process a PHP page?

Answer 1

Useless optimization

b. strip off comments to speed up code

Not a solid benchmark, but this particular post has great PHP performance tips and some mythbusters.

Answer 2

Comments are not parsed in PHP but rather ignored and PHP skips over them, in excess they only add to your diskspace. Otherwise, comments do not lag down processing at all.
