> I noticed that the file from PDFBOX-2035 needs 210 seconds on my new PC. The profiler shows that much time is lost in {{java.awt.geom.AreaOp.pruneEdges}}. A google search hit the linked SO issue. So I changed PageDrawer. Times on new PC with energy setting to maximum:
> - PDFBOX-1350: 53 secs before, 12 secs after
> - PDFBOX-2035: 210 secs before, 9 secs after
> - all tests: 424 secs before, 247 secs after (the difference is mostly because of PDFBOX-2035 which prevents termnination of the test)
> - all tests except the two: 246 secs before, 230 secs after
