When Idioms Meet Metrics: Evaluating Lisp Performance Through the nbody Benchmark

This article explores the critical tension between writing idiomatic, elegant Lisp code and achieving competitive computational performance on the nbody benchmark. For Lisp developers, it offers practical insights into whether following language best practices must inevitably sacrifice speed, contributing to the broader debate about language design tradeoffs. The findings have implications for functional programming advocates seeking to demonstrate that expressive code patterns need not compromise efficiency.
