Hello @koc-it-support ,
We’re sorry to hear that you’ve encountered this issue. From your message, it’s not entirely clear which GroupDocs.Total product you’re using — is it for .NET, Java, or are you referring to our online viewer?
Hi Thomas,
I was able to reproduce the bad performance of the pages 15 and 41 when rendering them to the HTML and PNG using GroupDocs.Viewer for .NET version 25.9 (latest at this moment). I can confirm your observations. I suppose that this performance penalty is related to the content of these particular pages - it is quite complex, especially the map on the page 41. Even if desktop programs like Foxit Reader the slow page 41 rendering may be visually observed during the document scrolling. Anyway, performance data is gathered and logged, developers are informed, and we’re waiting the response from them.
When any news will be available, I’ll inform you here immediately.
With best regards,
Denis Gvardionov
