Keith Devens says:  It turns out it's much faster to build large strings from many smaller strings by concatenating them onto one string than it is to append to an array repeatedly and then join that array into a string. I timed it and was surprised by the results.  But that's not Secret #812. Read what Joshua Paine has to say in that post's comments.
