High Memory Consumption when Saving PowerPoint Presentation in C#

Thank you for your reply,I have try to use your suggestion but it‘s without effect.

My example like this:

LoadOptions loadOptions = new LoadOptions
{
    BlobManagementOptions = new BlobManagementOptions
    {
        PresentationLockingBehavior = PresentationLockingBehavior.KeepLocked,
        MaxBlobsBytesInMemory = 1 * 1024 * 1024,
        IsTemporaryFilesAllowed = true
    }
};

I think there is no ‘big object’ in my ppt file.
I want to know why many Gen2 objects are generated after opening the ppt file.
It is difficult to release Gen2 objects, which eventually leads to memory rising.

The dockfile content as below:

FROM registry.edoc2.com:5000/edoc2v5/dotnet3.1-deps:runtime-deps-3.1-debian11-fonts-20211026
ARG source

WORKDIR /app
EXPOSE 6261
COPY ${source:-obj/Docker/publish} .


ADD docker-entrypoint-transport.sh /scripts/docker-entrypoint-transport.sh
RUN chmod +x /scripts/docker-entrypoint-transport.sh

RUN apt-get update
RUN apt-get install -y libgdiplus
RUN cd /usr/lib && ln -s libgdiplus.so gdiplus.dll
RUN apt-get update && apt-get install -y --no-install-recommends libc6-dev
RUN chmod +x ./MCode64
ENTRYPOINT ["/scripts/docker-entrypoint-transport.sh"]

I find a possible reason that causes memory rise when open the pptx file is the pptx file contains .svg file.

@celerycabbage2022,
Actually, this is a “normal” memory consumption at the moment, because there are a lot of resources in the presentation and we deserialize the whole model at once.

The issue has been blocked by another issue: partial loading of large presentations into memory. This is a priority issue and our developers will do their best to resolve it.

You mean after resolve partial loading of large presentations issue,my issue will be resolved automatic?
