Enable CDN to Load Applications 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.
This setting is disabled by default for orgs created before the Winter ’19 release, and enabled by default for new orgs and all new and existing Experience Builder sites. Lightning CDN for Experience Builder sites can’t be turned off and isn’t configurable.
From Setup, enter

Select the checkbox for “Enable Content Delivery Network (CDN) for Lightning Component framework”.
