Simple. Tr's faster, because it doesn't have to do all the funky "regex" style matching. Tr just loops through the characters one-by-one, and if it finds a + it changes it to a space. If it doesn't, it doesn't spend any more time figuring out what not to do, whereas s/// will. In other words, s/// is like using a power drill when a screwdriver would do.

Update: Okay, maybe it's not technically faster, but in theory it's supposed to be faster. I'm guessing that the s/// regex command gets more bit-level optimization than anything else in perl, just because it's such a swiss army knife of functionality; maybe tr got left behind on optimization?

"In fact, we must do just the opposite and remain ever-vigilant, striving to ensure that we stop the Urkels of tomorrow before they gain power. Only by demanding full accountability can we reverse the shameful legacy of man's inanity to man."
