Calculator performance: index list

Below is a list of all calculators in my collection for which I have calculated a calculator performance index.

In short, the performance index is a simple way to compare calcuting speeds between different calculators.

Note that the index for some devices can change dramatically depending on the used settings. The index listed on this site is the highest value I was able to achieve, not necessary the highest possible.
