Your first pair can be significantly different, depending on the relative performance of concatenation vs your I/O system. However, your second pair should always be identical, statistically speaking. They always compile down to identical opcodes, as chromatic pointed out. There's no point in comparing them to see which one is faster, because you're pretty much guaranteed not to get a statistically signicant difference, and if you ever do, you didn't. :-)
