Log Scheduled Tasks That Take Too Long
Measures how long each scheduled task (cron event) takes to run and records the slow ones under Tools > Slow Cron Tasks, so you can spot the plugin that makes WP-Cron sluggish.

Performance snippets for WordPress
Snippets that make WordPress lighter and faster: remove emoji scripts and embeds, control the Heartbeat API, limit revisions and load scripts only where they are needed. For developers and site owners chasing better Core Web Vitals.
Run WP-Cron From a Real Cron Job
Stops WordPress from checking for scheduled tasks on every page view; you trigger wp-cron.php from your server's cron instead, which is faster and more reliable.
Send Emails in the Background
Queues emails sent by WordPress and plugins and sends them a few seconds later through WP-Cron, so form submissions, orders and registrations no longer wait for the mail server.
Spawn WP-Cron Less Often
Lets WordPress start its background task runner at most every five minutes instead of every minute, reducing extra requests on busy sites.
