WP-Cron performance

Use this file when cron causes spikes or request-time slowness.

Backend-only tools:

• wp cron test (spawning health)
• wp cron event list
• wp cron event run --due-now

Reference:

• WP-CLI cron command package: https://github.com/wp-cli/cron-command

Fix patterns:

• De-duplicate scheduled events and reduce frequency where possible.
• Ensure tasks are idempotent and short.
• Move heavy work off-request; cron that runs on page load can hurt TTFB.
