PPTX to PDF: Long time 3-10 minuets needed to export (Java)

Hi, I’m converting an pptx document with size 30M to pdf and it takes about 3 minutes to complete using aspose-slides-16.10.0 and about 5 minutes using aspose-slides-20.1-jdk16.jar.
I think the it is too long for me
Are there any settings I can modify to reduce the amount of processing time?
here is my example code:

PdfOptions opts=new PdfOptions();
opts.setJpegQuality((byte)90);
opts.setSaveMetafilesAsPng(true);
opts.setTextCompression(0);
Presentation ppt = new Presentation(“test.pptx”);
ppt.save(“test.pdf”, SaveFormat.Pdf, opts);

sorry, I missing pass opts into save method
ppt.save(“test.pdf”, SaveFormat.Pdf);

after I pass the opts into save method, the processing time reduce to 75 seconds,
ppt.save(“test.pdf”, SaveFormat.Pdf, opts);

My environment
