## Which programs are fast?

### How many times slower than the fastest

For 10 different tasks — How many times slower, the fastest benchmark programs for selected programming language implementations are, compared to the fastest written in any of the programming languages.

You can see that **the order would be different** if it was based on the median scores instead of the [pdf] geometric mean scores.

The boxes are broken into separate groups, at the minima of the kernel density estimate for the geometric mean scores.

Notice which boxes have no overlap; notice which boxes **overlap completely**. Notice which show little midspread; notice which spread across too large a range of values for confidence.
