Remote Cache Hit Rate measures the percentage of build and test tasks that are served from a shared remote cache rather than being rebuilt from scratch. High hit rates dramatically reduce CI/CD pipeline duration and compute costs by reusing previously verified artifacts. A declining cache hit rate may indicate cache invalidation issues, configuration drift, or non-deterministic build steps that undermine caching effectiveness.
Percentage of tasks served from cache. Misses force expensive full re-execution.
Critical multiplier for CI speed. With high cache hit rates (>90%), most CI runs complete in seconds. Bazel, Nx Cloud, and Turborepo all support remote caching. Cache poisoning is a security concern. One team reported 60% reduction in CI compute costs from caching alone.
Remote caching ROI scales with team size. More developers = more cache hits from shared computation. One team reported 60% reduction in CI compute costs.
High cache hits (>90%) mean most tasks return cached results in seconds. Cache miss = full execution.
Cached build artifacts skip compilation entirely. Remote caching shares across all developers and CI agents.
Near-instant builds from cache feel magical. Transforms monorepo from liability to advantage.
