the comments are parsed by the parser and can be extracted/used for doc building
etc - this means there is some overhead for commented files.
if you use an opcode cache then the overhead is only relevant at the time
a source file is compiled into opcodes (I don't know any opcode cache that
doesn't strip out the comment tokens from the compiled code)
in real life you won't notice the overhead at all.
and people will love you if you'r files are 90% comments :-)
