[jira] [Created] (PDFBOX-4869) Reading standard 14 fonts is slow

Alfred created PDFBOX-4869:
------------------------------

             Summary: Reading standard 14 fonts is slow
                 Key: PDFBOX-4869
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4869
             Project: PDFBox
          Issue Type: Improvement
          Components: Parsing, Text extraction
    Affects Versions: 3.0.0 PDFBox
            Reporter: Alfred


I ham testing text extraction from PDF and profiling the execution.

I found that the second biggest time consumer is the static code in Standard14Fonts that loads fonts from the pdf box jar.

The culprit seems to be the direct use of the stream returned getResurceAsStream.

Using a buffered stream around it reduces the load time a lot.
