Optimizely Performance Edge is a faster way to deliver client-side web experiments that takes advantage of a distributed network called "the edge." Performance Edge is designed to improve page performance by performing targeting and variation assignment tasks at the Edge instead of in the browser.
You have a unique Optimizely endpoint available to you at the Edge. It not only buckets your users into experiments and variations, but also returns only the changes needed to power those experiments and variations on the current page. Asynchronously, it also loads an Optimizely tracking snippet to log visit and conversion events on the page.
Performance Edge takes advantage of the structure of modern content delivery networks (CDNs) to deliver experiments to your visitors faster.
Content that's delivered from a server located close to a website visitor is faster than content delivered from one farther away. A CDN speeds up visitors' experiences of a webpage by placing servers all over the world, often near metropolitan centers.
Optimizely delivers experiments via a CDN. The traffic is routed through servers that are geographically close to your visitor.
Performance Edge is a fast, smart delivery method because microsnippet is lightweight. It contains only the content needed to deliver experiments to a specific visitor on a specific page.
The heavy lifting of experiment computation is moved out of your visitor's browser and into distributed machines all over the world, reducing page load time and making it possible to deliver fast, smart experiments to your site visitors no matter where they are.
