Performance Issues with Aspose PngDevice on Linux

We are rasterizing customer invoice PDFs to PNG using Aspose.PDF. However, there are 2 issues with it that seem to be worse on linux compared with Windows.
Please see the basic attached example PDF in an archive compressed and split to avoid attachment size limit.

  1. Processing time is slow (13 seconds on windows and 24 seconds on linux)
  2. Process memory usage increases on linux and does not return to the baseline after processing is done. We have tried calling PDFDocument.Dispose(), also.
    This increase is more notable with documents containing multiple pages and after processing multiple documents. Note sure if this is related to PDFNET-46106.
