Which programs are fast?

How many times slower than the fastest

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.

Toy benchmark program elapsed seconds compared to the fastest for more programming language implementations.

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

Toy benchmark program elapsed seconds compared to the fastest for different programming language implementations.

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

Notice which boxes overlap completely. Notice which spread across too large a range of values for confidence.
