Extracting text from 1 page takes extremely long time

The attached PDF takes extremely long time for Aspose.PDF for .NET 21.2 to extract text from one page. Another PDF library can extract the text in about 10 seconds. Is there any way to improve the speed?

Code:

var pdf = new Aspose.Pdf.Document("input.pdf");
var absorber = new Aspose.Pdf.Text.TextAbsorber();
pdf.Pages[1].Accept(absorber);

File: input.zip (2.3 MB)
