wp-performance

You can profile WordPress backend performance using WP-CLI commands and the Node.js perf_inspect script. This approach analyzes slow admin screens, REST endpoints, and scheduled tasks via server-timing data and CLI profiling without relying on browser UI.

The best way to diagnose slow WordPress admin pages and heavy cron tasks is running a guided measurement workflow. Start with baseline checks using wp doctor check, then generate a backend profiling report to identify bottlenecks in autoloaded options, DB queries, and HTTP calls.

Yes, you need both WP-CLI and a Node.js runtime to run these WordPress performance diagnostics. The profiling workflow requires WP-CLI for baseline checks and the Node.js perf_inspect script to generate backend profiling reports, along with access to a WordPress install via --path and --url.

Yes, you can use server-timing headers and REST envelopes to analyze WordPress REST endpoint performance. The profiling workflow leverages server-side timing data and Query Monitor REST envelopes to identify bottlenecks in slow REST endpoints across dev, staging, and production environments.

Using WP-CLI profiling, you can identify WordPress performance issues related to autoloaded options, database queries, cron tasks, and HTTP calls. The guided workflow progresses from baseline checks to deep profiling, enabling targeted optimizations for slow admin screens and REST endpoints.

Yes, WordPress backend profiling works across development, staging, and production environments. The CLI-based profiling approach uses scripted diagnostics with WP-CLI and server-timing data, making it repeatable and safe to run in any environment with access to the WordPress install via --path and --url.
