Do the comparison (basic setup, no changes for the comparison tool). It takes quite a bit. Now I am aware that with 2000 elements, there are 4 million comparisons (and if it is based on size, datestamp, name it is 3 times 4 million), but they should be a breeze on whatever CPU that is not from the 90s. Instead on a A10 cpu (https://en.wikichip.org/wiki/amd/a10 5750M) it takes between 10 to 15 seconds to compare. Of course it is not that tragic, but could it be improved or is it really "nice to have" ?
