High memory consumption during a document saving


Hi Support,
We encountered a memory problem (high consumption) during the saving of a document.
I will attach a simple program to replicate the issue:
After the document opening, the memory is 250 MB, when the document is saved it reaches 1 GB.

I have worked with the sample project shared by you and like to share that amount of memory consumed is dependent on size of presentation, number of slides and number of shapes inside slide especially multimedia contents and charts. Your presentation have considerable number of slides as well as chart contents inside it. When presentation is loaded its Document Object Model (DOM) gets loaded in memory and it involves loading of different statistics as well extraction of presentation in DOM. Additional memory is required upon saving or rendering the presentation as well. I hope the shared elaboration will be helpful.


Hi Mudassir,
I modified the “Input.pptx” keeping only the PowerPoint tables and the issue persist.
In my opinion, the management of PowerPoint table has a memory problem.
Please try again using the attached file.
