Please give a brief summary of your issue:
Switching between tabs in Multi-Tab mode of version 10 is slow compared to 8.5
Please describe your issue and provide steps to reproduce it:
I tried to update WebViewer 8.5 to version 10.0.0, leaving my API calls untouched.
All calls work fine, but when using Multi-Tab mode, version 10 is really slow when switching between tabs.
There is a noticeable delay between clicking on a tab and the document being displayed in that tab.
Using the API method instance.UI.TabManager.setActiveTab() also became slower.
This is also the case in the showcase on the Apryse website.
In version 8.5, switching between tabs worked with almost no delay.
In the browser developer tools, I also noticed that WebViewer 10 loads lib/core/pdf/lean/PDFNetCWasm.br.wasm while Version 8.5 uses the optimized WASM file lib/core/pdf/lean/optimized/PDFNetCWasm.br.wasm.
I’m NOT using the Full API and I didn’t change my code while comparing WebViewer Version 10 and 8.5.
What is the reason for the slow performance?
As it is now with version 10, users are certainly not enthusiastic…
