Building Really Fast Applications
summary
Claims building apps that responds in less that 15ms and shows concrete wins: a custom middleware runner and tiny kernel, a redirect geocoder proof‑of‑concept, and Symfony components wired for speed. Uses cache chain (memory → APCu → Redis), doctrine fixes (add index drops a 200ms query to <1ms, select only needed columns, and use the new keyword DTO projection), lazy services (1,500 normalizers → 20ms saved), OPcache tuning, background jobs, and profiling with Blackfire to verify improvements. Tools like RoadRunner/Swoole via the Symfony Runtime keep processes warm.
