Which programs are fastest?

… a pretty solid study on the boredom of performance-oriented software engineers grouped by programming language.

To fix this, regex crate must be updated or replaced. I spent two weekends on this.

Maybe programs contributed to the project as part of a concerted language advocacy and marketing strategy, benefit from more programmer hours spent on program optimization. Always look at the source code.

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 busy seconds compared to the fastest for more programming language implementations.

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

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

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

Which programming language is fastest?

Should we care? How could we know?
