High CPU for long time while rendering files with Aspose

We are using Aspose to render PDF & Office files (docx,pptx,xslx + old versions) .
when performing the rendering process for files which contains multiple pages, images with 20mb+ size the CPU value increase to 100% for a long time until our app get stuck.

for now, we killed the process after some time automatically so we didn’t get the file render.

do you have a solution to this problem?
(I also can send a problematic file for an example)

Thank you.


It is quite difficult to answer such questions because CPU performance and memory usage all depend on complexity and size of the documents you are loading/generating.

It hardly depends on local environment. It can be completely different for a server that generates thousands documents 24/7 or for a local PC that generate only the one document by demand.

Could you please share your working environment along with following detail for testing?

  • Your input documents.
  • Please create a standalone console application ( source code without compilation errors ) that helps us to reproduce your problem on our end and attach it here for testing.

As soon as you get these pieces of information ready, we will start investigation into your issue and provide you more information. Thanks for your cooperation.
