Both Mirage and RocketLoader appear to serve their respective scripts from a Cloudflare domain rather than from our own domain via CDN. The additional SSL handshakes required is causing a noticeable performance hit.
Is this by design?
If so, is there a workaround?
I can’t imagine these tools having a positive performance effect except on sites with the gravest of baseline image/cwv performance.
This is effectively what Rocket Loader does, however, your scripts might not necessarily work in this situation, and you might have a complex setup that prevents you from moving the scripts further down the page…
May I ask where exactly? Which tool have you used and what did you measured so far?
Any other user/visitor reporting the same issue, or that’s just a assumption based on a report from some online tool measuring multiple factors for page load time?
I’d check with a real 3G/4G or slower network mobile phone
