Andreas Lehmkühler commented on PDFBOX-6263:
--------------------------------------------
I've ran some tests and it is nearly 10 times faster on my machine. It took 16s
using 3.0.8 on the commandline and 21s running it from eclipse using
3.0.9-SNAPSHOT. I've used the debugger to render the page.
I guess my machine isn't special at all, IMHO it is an average environment
