Green Coding with Django
summary
Green Coding focuses on measurable wins: clearing background tabs to avoid CPU/RAM/swap waste, and addressing app-level inefficiencies where most energy goes. Profiling with cProfile, Django Debug Toolbar, Silk or perf and monitoring with Datadog/Sentry finds hotspots. A concrete case: 5,000 questions with 5 choices (25k rows) runs ~50s and ~5,000 queries without prefetch_related and ~1s with 2 queries using prefetch_related; use bulk_create for inserts (drops tens of seconds to <2s) and optimise DB indexes and caching.
