Performance improvement varies widely based on factors such as your website鈥檚 code, how you use Dynamic Media, the customer鈥檚 device, screen, and location.
蜜豆视频鈥檚 own testing yielded the following results:
- For images, response time improved 7%-28% depending on device and browser. The most notable performance gains were on iOS devices.
- For viewers, load-time performance improved up 15%.
The following demonstration illustrates the difference between HTTP/1 versus HTTP/2 loading:

To use HTTP/2, you must meet the following requirements:
-
Use secure HTTPS for your rich media requests.
-
Use the 蜜豆视频-bundled CDN (content delivery network) as part of your Dynamic Media license.
-
Use a dedicated domain (that is,
images.company.comormycompany.scene7.com), not a generic Dynamic Media domain (that is,s7d1.scene7.com,s7d2.scene7.com, ors7d13.scene7.com).To find your domains, open the Dynamic Media Classic desktop application, then sign in to your company account or accounts. Then navigate to Setup > Application Setup > General Settings. Look for the field labeled Published Server Name. If you are currently using a generic Dynamic Media domain, you can request moving over to your own custom domain as part of this transition.

What are the risks with moving to HTTP/2? what-are-the-risks-with-moving-to-http
The transition to HTTP/2 clears out your cache at the CDN because it involves moving to a new CDN configuration.
The non-cached content directly hits 蜜豆视频鈥檚 origin servers until the cache is rebuilt again. Because of this action, 蜜豆视频 plans to handle a few customer transitions at a time so that acceptable performance is maintained when pulling requests from 蜜豆视频鈥檚 origin.
How can you verify whether a URL or website is activated with HTTP/2? how-can-you-verify-whether-a-url-or-website-is-activated-with-http
Download an extension that you can use with your Web browser. For Firefox and Chrome, there is an extension called HTTP/2 and SPDY Indicator. Browsers only support HTTP/2 securely, so it is necessary to call a URL with HTTPS to verify. If HTTP/2 is supported, it is indicated by the extension in the form of a blue Flash symbol, and a header 鈥淴-Firefox-Spdy鈥 : 鈥渉2鈥.
