This repository contains implementations of a 'swapview' program that displays Linux process swap usage in many different programming languages. Each implementation reads from the /proc filesystem to gather swap information for all processes and outputs a formatted table sorted by swap usage. The project includes a top-level Makefile to build all implementations, benchmarking tools (bench.py and a Rust-based benchmarker) to compare performance across languages, and result files showing historical performance data. The code serves as both a practical utility for monitoring swap usage and a comparative study of language performance and idioms.
