When this matters
Without caching, PHP code is repeatedly parsed, and during traffic peaks process queues and slowdowns are more likely.
Explanation of PHP-FPM and OPcache: PHP process handling, bytecode cache, lower load and diagnostics.
Practical checklist
- enable OPcache for compatible applications
- check process and memory limits
- avoid too many heavy plugins
- monitor response time after changes
