i don't need external programs screwing my code up. it's more efficient than any "optimiser" could make it anyway. you'd have to be a really sloppy coder to have to rely on an "optimiser" to get your code working as it should.
also, the whitespace makes such a minuscule difference that it doesn't matter, and well-formed code is much more important than the 0.2ms difference that unreadable markup would make. a newline is only two characters, in the end.
it's not my code that is slow, it's the server itself.
