Aspose.pdf for Java. Save is slow on some documents

Save of some PDF documents are slow in aspose-pdf 20.7 and later (tested with 20,6, 20,7, 20.8 and 20.9). Attached document woks fine with aspose-pdf 20.6 and earlier.

Document document = new Document(filename);
long startSave = System.currentTimeMillis();
document.save(newFilename);
long endSave = System.currentTimeMillis();
System.out.format(“save: %d ms%n”, endOpen-startOpen, endSave-startSave);

Result for attached document. All test run with Java 8:

  • 20.8: save: 93009 ms
  • 20.7: save: 89004 ms
  • 20.6: save: 4100 ms
