> Project: PDFBox
> Issue Type: Improvement
> Components: Parsing, Text extraction
> Affects Versions: 2.0.20, 3.0.0 PDFBox
> Reporter: Alfred
> Assignee: Tilman Hausherr
> Priority: Major
> Labels: Optimization
> Fix For: 2.0.21, 3.0.0 PDFBox

> Attachments: PDFBOX-4869.patch

> Original Estimate: 1m
> Remaining Estimate: 1m
>
> I am 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.
> That would be a ZipInputStream when using PDFBox as a jar.
> Using a buffered stream around it reduces the load time a lot.
