most performance-focused customers
DID YOU KNOW? Full Stack is Optimizely’s server-side experimentation product that integrates with your stack via SDKs. If you want to remove the performance
trade off above, and are staffed with engineers or product development teams that don’t require a visual editor, you should consider Optimizely Full Stack.

14. —Kyle Rush, VP of Engineering
“We recently deployed a change to casper.com
that loaded Optimizely from our own server
instead of their server. This change shaved 1.7
seconds off of the start render time.”
Casper initially evaluated the option to load Optimizely asynchronously. But their
Product Management team pointed out the potential flash of unstyled content (FOUC)
effect would be a bad customer experience. So, the next best thing they decided was
self-hosting. Just through self-hosting, they were able to see significant improvements.
