Fast checklist for plugin performance
Start with a measurement-first mindset: profile your plugin early, then reduce work where it matters. Focus on minimizing database hits, shrinking frontend assets, and moving heavy work out of request cycles. Below is a concise, practical plan you can apply during development to keep performance predictable and scalable.
- Benchmark and profile. Establish a baseline for page load, memory, and query count so improvements are measurable.
- Reduce database queries. Avoid repeated queries in loops, use efficient WP_Query or direct prepared statements when needed, and prevent autoloaded options from growing unbounded.
- Cache strategically. Use object caching and transients for expensive results and implement clear invalidation rules instead of caching everything blindly.
- Load assets conditionally. Enqueue scripts and styles only on pages where they’re required and consider bundling/minification as part of your build process.
- Move long tasks to background. Offload imports, exports, and heavy processing to background jobs or queued workers.
- Design efficient endpoints. For REST or AJAX handlers, paginate, limit fields, and validate input to avoid unintentionally large payloads.
- Limit external calls. Batch and cache responses from third-party services and provide sensible timeouts and fallbacks.
- Test under realistic conditions. Use staging and load testing to catch bottlenecks before release.
