PDF Embed Incredibly slow

[Garrett28259082qfbf]

PDF Embed SDK has changed with Full_Window implementation where PDF is incredibly slow to load. It used to load hundreds of pages immediately using URL, but now via network tab it is loading a bunch of images every time you scroll to a different part of the document.

Also,

there is a new "Loading" indicator here

@Raymond Camden this was a big breaking change to our app

[Raymond Camden]

got a link to where i can see this?

[Raymond Camden]

i just uploaded a 250+ page PDF to the Embed playground and I could see no slowdown.

Messaged you loom video privately

[Raymond Camden]

I can see what you mean - but am unable to reproduce. Could you also share that PDF to me privately? Instead of DM here on the forums, just email me jedimaster@adobe.com.

The same pdf is working fine on our NextJS marketing site, but using a Blazor Server-side app it's not

[Raymond Camden]

Than it's possible the issue is on your side, right? Are you streaming the PDF data to Embed perhaps and Blazor is doing it slowly?

[Garrett28259082qfbf]

I pass the PDF viewer a URL, it should only be happening client side

[Raymond Camden]

That's fair, but if the client side code is (roughly) the same and the difference is your server, wouldn't it make sense it's something on your server? You say you pass the URL to PDF. If you open the PDF directly in a tab, the one loaded via Blazor, perhaps its loading slowly there.

[Garrett28259082qfbf]

Seeing a lot of cancelled requests when its loading

[Garrett28259082qfbf]

It's only one PDF, i emailed you the copy

[Raymond Camden]

Unfortunately, unless you can set up something I can test publicly, maybe sit up a Blazor app in a public way, I won't be able to reproduce this. I don't want to 100% blame the server, but we need a way to reproduce this. I'm just not seeing any issues via our Playground and large PDFs.

[Garrett28259082qfbf]

I don't, it's behind auth0.
