Just for fun I removed the extra concat on the stringbuilder and upped the cycles to 20 and 20,000.

Running it several times showed that the 20 cycle loop was fairly close, where the 20,000 loop was not even near close.

    0.0000089 vs. 0.0000092

and

    0.9846729 vs. 0.0006852

Edit: I also changed them both to add a fixed string, since I don't have enough memory for a 4 * 2^20,000 length string.
