Quicksort which works by sorting string pointers only instead of the strings themselves. In particular for long strings around 1000 chars there is a 15 times improvement in speed, going up to 100 times for really long strings, and speed is almost indepent of string length; one million strings are sorted in under five seconds. For short strings below 10 chars or so speeds are more or less identical. The screenshot shows the compiled timing.
