Ruby Optimise
This is a comprehensive performance optimization reference for Ruby with 42 rules across 8 categories, from object allocation and ActiveRecord queries to string handling and runtime configuration. Each rule is prioritized by impact and prefixed for quick lookup, making it practical for code reviews or refactoring sessions. The organization is solid: CRITICAL priorities cover allocation patterns and collection processing where Ruby apps typically bleed memory, while lower tiers handle concurrency and GC tuning. What's useful here is the specificity. Instead of vague advice, you get targeted rules like using find_each for large record sets or enabling YJIT in production, each with its own reference file for examples and context.
