Andreas Lehmkühler commented on PDFBOX-5779:
--------------------------------------------
I can't confirm such huge differences when running the code.
Using 2.0.31-SNAPSHOT I got 2400ms (file) vs. 3300ms (stream). Following
Maruans suggestion to wrap the FileInputStream in a BufferedInputStream speeds
up the test and it now takes 2900ms.
Saying that, IMHO there isn't see any real regression here.

> Project: PDFBox
> Issue Type: Improvement
> Affects Versions: 3.0.1 PDFBox

> Priority: Major
> Attachments: arial.ttf, pdfbox-1.java, pdfbox.java

> Run the attached program, then open the code on line 41 and comment out the
> code on line 44, and compare the time consumption of the two font loading
> methods.
> Why does using font streams have poorer performance compared to using font
> files? Is this a limitation? If I can only use font streams, are there any
> ways to improve performance?
