FAQPage Schema
How do I profile WordPress backend performance without a browser UI?▼

You can profile WordPress backend performance without a browser UI by running the dedicated perf_inspect script via WP-CLI, collecting server-timing data and REST headers to measure slow pages.

What is the best way to diagnose slow database queries in WordPress?▼

The best way to diagnose slow database queries in WordPress involves using backend profiling tools to inspect autoloaded options and query execution times, identifying bottlenecks without browser-based interfaces.

Can I use WP-CLI to check WordPress cron tasks and external HTTP calls?▼

Yes, you can use WP-CLI to check WordPress cron tasks and external HTTP calls by running a perf_inspect script that collects deterministic measurements from backend contexts.

Does this backend profiling approach work with headless WordPress setups?▼

Yes, this backend profiling approach works with headless WordPress setups by collecting headless data, server-timing metrics, and REST headers to guide performance improvements.

Why do I need server-timing and REST headers for WordPress performance optimization?▼

You need server-timing and REST headers for WordPress performance optimization because they provide deterministic measurement data required to accurately target and resolve backend bottlenecks.

What are the limitations of profiling WordPress performance without a browser UI?▼

Profiling WordPress performance without a browser UI limits diagnostics to backend contexts, targeting server-side elements like database queries and cron tasks rather than frontend rendering issues.
