Enable CDN to Load Lightning Experience Faster

Load Lightning Experience and other apps faster by enabling Akamai’s content delivery network (CDN) to serve the static content for Lightning Component framework. A CDN generally speeds up page load time, but it also changes the source domain that serves the files. If your company has IP range restrictions for content served from Salesforce, test thoroughly before enabling this setting.

Where: This setting affects Lightning Experience and other apps that are built on the Lightning Component framework. This setting doesn't affect any version of the Salesforce app. This setting doesn’t affect Lightning communities.

Why: CDNs improve the load time of static content by storing cached versions in multiple geographic locations. This setting turns on CDN delivery for the static JavaScript and CSS in the Lightning Component framework. It doesn’t distribute your org’s data or metadata in a CDN.

How: This setting is disabled by default for existing orgs and enabled by default for new orgs.

To enable CDN, from Setup, enter Session in the Quick Find box, and then select Session Settings. Select Enable Content Delivery Network (CDN) for Lightning Component framework, and click Save.

If you experience issues, ask your IT department if your company’s firewall blocks Akamai CDN content.
