I just rewrote a piece of code and tested it against a ridiculously huge dataset (63,000 points), just to see how much it has improved. The new code ran under 14 seconds. The old one – well – all I know is that it’s taken more than nine minutes and is still running.
Success is a nice feeling.
Update: It ended up taking 14 minutes and 53 seconds. More than a 10x 60x speedup.
