PHP Performance, Dependencies, Deployment & Observability

OPcache Configuration

OPcache stores compiled bytecode in shared memory, eliminating parse/compile per request. Typical 3-10x throughput gain.

; Production OPcache config
opcache.enable=1
opcache.memory_consumption=256
opcache.max_accelerated_files=20000
opcache.interned_strings_buffer=16
opcache.validate_timestamps=0       ; MUST restart FPM on deploy
opcache.save_comments=1             ; Required by Laravel/DI containers

// ❌ Bad: No OPcache monitoring — silent degradation when cache is full
// Deploy and hope for the best
