High memory usage with "Remove unused streams" optimization

Aspose.PDF Product Family
1

Hi,

We found that using following code:
using Aspose.Pdf;
using (var pdf = new Document(“Big.pdf”))
{
pdf.OptimizeResources(
new Document.OptimizationOptions { RemoveUnusedStreams = true }
);
}
On attached file:
Takes ~25 times more RAM than without RemoveUnusedStreams.
With RemoveUnusedStreams = true peak RAM usage is 1600 Mb (!!!)
With RemoveUnusedStreams = true peak RAM usage is 60 Mb

Please, note issue can be reproduced with any pdf file.

Same issue already posted here https://forum.aspose.com/t/72168.
