Google pagespeed reporting UEM JS as blocking
https://developers.google.com/speed/pagespeed/insi...
Google page speed for our site is reporting UEM JS as blocking JS. My understanding is that dtagent JS is asyn call and its not blocking. Any idea why google would report that?
Actually page speed is correct. The javascript agent must be loaded as blocking script, to ensure that it is the first script to be loaded. This is important because otherwise the agent would not be able to instrument all the supported javascript frameworks and also it would be too late for timings that the agent calculates in addition to the standard W3C timings. Right now it looks that there is no way around the blocking script without losing the level of detail.
