Very low Start Render times - error?
Recently, we're seeing some very low numbers on Start render time, which doesnt seem realistic, wondering if its a problem in WPT, or if Chrome has changed the way it reports Start render time?
Start Render occurs before download of html document is complete, before css files have even started download, around 200ms. Normally, our Start Render is around the 2s mark.


We are using akamai edge start to get the very fast ttfb, which only includes HEAD element with css refs and dns prefetch, then the rest of the html follows later, with download complete around 500ms.

How can Start Render occur before html body is downloaded?
Has anyone else seen the same thing?
