Simple Recipes to Enhance Developer Productivity
summary
Large monorepo of ~2 million lines and 294 modules with ~150 builds/day and 110 contributors reduces PR build time from ~68 to ~27 minutes — a 61% total win — by combining concrete steps: enable Gradle parallel and build cache, tune JVM heap (XMX/XMS heap sizing and max workers), remove unused/outdated dependencies and add automated updates, and fix CI: warm faster agents, cancel redundant commits, install a Jenkins build-avoidance plugin and parallelize CI stages and Gradle tasks.
