Advanced
Speculative loading for instant page transitions, and serving static assets from a CDN.
These settings apply to the whole site, so a change here is visible on every page that uses the feature. Find them under Canvas > Performance, in the Advanced tab.
The tab sits in the rail on the left of the screen, with its own panel beside it:
This group holds the following settings:
Speculative Loading (Instant Pages)DefaultOff
Use the Speculation Rules API to prefetch or prerender same-origin links before click. Creates near-instant page transitions on Chromium browsers.
Speculative Loading ModeDefaultPrefetch
Prefetch downloads the HTML; prerender also executes JS, giving true instant transitions.
