WordPress Performance Tips
by Austin Ginder
Performance !== Pagespeed
Performance Tip #1:
WP-Cron improvements
WP-Cron handles scheduled background tasks.
By default WordPress runs cron checks on every page load which is not ideal for:
- low traffic websites
- high traffic websites
Recommendation
Disable WP-Cron and enabling server level cron
Add the following to wp-config.php
define( 'DISABLE_WP_CRON', true );Enabling server level cron
Over SSH type crontab -e and add the following. Make sure to change the domain to your website.
10,25,40,55 * * * * curl -kILs -H 'Host: captaincore.io' https://localhost/wp-cron.phpExit and save changes. Run crontab -l to confirm new server level cron.

Performance Tip #2:
Reducing Database Autoloading
What is autoloaded data?
WordPress databases comes with an options table and entries in this table can optionally be marked for autoload.
If the amount of data being autoloaded becomes excessive, more than 10MB, it can cause performance issues or out of memory errors.
