PlummersSoftwareLLC/Primes

Primes is a benchmark collection that implements the same prime number sieve algorithm across more than 100 programming languages to compare their execution speed and code approaches.

The project solves the problem of objectively comparing programming language performance by using a standardized algorithm—the Sieve of Eratosthenes—implemented consistently across many languages. This approach isolates language and runtime performance characteristics by holding the algorithmic problem constant, allowing developers to see how different languages handle the same computational task. The repository includes tooling for automated builds and daily benchmarks, with results viewable through an in-browser application that lets users filter and sort performance data across languages and implementations.

The project suits anyone interested in language performance comparisons, whether for educational purposes, technology selection, or curiosity about how different languages tackle the same problem. It works well for developers evaluating multiple languages or seeking concrete performance data rather than anecdotal claims. The collection accepts community contributions, so it grows through submissions of alternative implementations and language additions. The in-browser PrimeView application makes results accessible without requiring local setup, though developers can also run benchmarks locally using the provided Makefile.

The project maintains active community engagement through accepted pull requests for new solutions and improvements. Benchmark execution is automated across multiple machines, with results updated regularly to reflect current performance characteristics.
