[jira] [Updated] (PDFBOX-4869) Reading standard 14 fonts is slow
[ https://issues.apache.org/jira/browse/PDFBOX-4869?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alfred updated PDFBOX-4869:
---------------------------
Description:
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.
That would be a ZipInputStream when using PDFBox as a jar.
Using a buffered stream around it reduces the load time a lot.
