This is a pretty ubiquitous discussion topic on this forum if you dig around. In a nutshell, there's no way to know this, but there are workarounds. You can try caching/preloading the QR code data and feeding that into the popup as a parameter or session property. Or you can try increasing the websocket max message size in your `ignition.conf` file (if you are at or above version 8.1.12). As a disclaimer, I haven't tried either of these, and you might find no improvement. You can try using a `coalesce` on your binding(s) which is frequently recommended here -- I have tried this but ended up scrapping it because the coalescing itself needs time to evaluate and I personally saw no improvements. What I started doing is just putting a delayed fade-in style class on any complex components that need time to load or creating an interstitial loading screen.

The view is a composition of many different containers, each with a tag binding on the display property: at first loading the UI experience is not the best indeed, because you see all containers for a short while, which then disappear as soon as bindings come into action - some portions show at first the Bad/error overlay, because their display depend upon expressions on tags.

The property assignment is instantaneous, but after the assignment there are several factors which all add to the amount of time: The Gateway has to send all of the data to the browser through the websocket. Like a pipe, there’s only so much data which can be sent at one time - the data sort of backs up and comes through in chunks.
