Years of testing in hundreds of thousands of installations have helped us learn how to make caching behave well with WordPress. The tradeoff is that disk enhanced page cache performance under load tests will be decreased by ~20% at scale.', 'w3-total-cache' ); ?>
  4. Recommended: On the "Minify" tab all of the recommended settings are preset. Use the help button to simplify discovery of your CSS and JS files and groups.

  6. Recommended: If you already have a content delivery network (CDN) provider, proceed to the "Content Delivery Network" tab and populate the fields and set your preferences. If you do not use the Media Library, you will need to import your images etc into the default locations. Use the Media Library Import Tool on the "Content Delivery Network" tab to perform this task. If you do not have a CDN provider, you can still improve your site\'s performance using the "Self-hosted" method. On your own server, create a subdomain and matching DNS Zone record; e.g. static.domain.com and configure FTP options on the "Content Delivery Network" tab accordingly. Be sure to FTP upload the appropriate files, using the available upload buttons.', 'w3-total-cache' ); ?>

  8. Optional: On the "Object Cache" tab the recommended settings are preset. If using a shared hosting account use the "disk" method with caution, the response time of the disk may not be fast enough, so this option is disabled by default. Test this option with and without database cache to ensure that it provides a performance increase.', 'w3-total-cache' ); ?>
