GNOME Bugzilla – Bug 630012
removing pages in big documents is really slow and hangs the GUI

Take a PDF with many pages (let's say 900), then try to remove the last 800 pages or so. PDFMod will max out the CPU (in my case, two of my cores) for a really long time while pdfmod's UI hangs. I know this isn't the optimal way (I guess you're supposed to "extract" pages), but surely this is a symptom of something that can be optimized. Version 0.8.3.
I was just working on this code the other day and found the problem: we re-save the PDF after removing each individual page, instead of after removing all of the. Should have a fix for this soon. Thanks for reporting the bug!
Fixed in master
