To use Spreadsort, you can download the release and either run it as-is, or use tune.pl to tune the variables to your system and get slightly better results, along with providing a regression test to verify that the sorting is correct on your system. tune.pl takes a long time to run (a few hours), and if you're often sorting data significantly larger than 10 million elements, I recommend increasing the size of what tune.pl works on to tune for that size, which will make it take longer.
The average user who just wants to plug in a faster sorting algorithm is probably best off just downloading Spreadsort and using it as-is.
