Github Viewer Demo

I’ve successfully downloaded, installed, and complied the web form front end demo… but why is it so slow with loading each page? The preview image for each page literally takes like a minute to load.



I haven’t modified anything in the downloaded code, just loaded it to see how it looks and works.

Hi there,


Thanks for taking interest in GroupDocs.Viewer for .NET.

Please note that document rendering and loading time depends on multiple factors such as document’s content which can include text, images, tables; amount of resources that application can use; server loading time, RAM and so on. Furthermore, first time the application may not show the real performance results as it is considered as a warm up. Please try to run the application more than 1 time to get the real performance results. For more information, please have a look at performance profile of GroupDocs.Viewer for .NET 17.4.0.

In case you would have any other queries, please do let us know.

Have a nice weekend ahead.
Warm Regards

Yes, I know that, and I know the first compile always takes the longest; however, while it was running without closing it I ran several documents through it, clicked on the other thumbnails, and it still took a long time to load.



Short of publishing it… is there anything else I should be looking for as I would really like to see this work.

Hi again,


Thanks for your response.

As I mentioned in the previous post that the rendering and loading time depends on multiple factors including the hardware specifications. We recommend you to upgrade your hardware to get the better results. Furthermore, when GroupDocs.Viewer cache is enabled (ViewerConfig.UseCache = true) and you render document for the first time, it consumes more resources and time than when you render document for the second time. In this case, GroupDocs.Viewer extracts data from the cache. In case you would have any confusion, please do let us know.

Warm Regards
