Making CocoaPods Fast with Modern Ruby Tooling
summary
Claims a half reduction in pod install time and a 90 second savings by changing under 200 lines of code, validated on large apps that hit ~395 pods. Uses sampling and tracing profilers like rbspy and rubyprof plus a custom timing tool chronometer to find a graph traversal bottleneck, implements a memoization DSL and build settings refactor, ships incremental-installation cache files that save up to a minute, and shows architectural limits remain at scale.
