#Poppler, the #FreeDesktop #PDF library used by #Evince / #Okular / #GNOME #Papers & pretty much every floss PDF reader app on #Linux, has always been slow at searching text. As in, "3 to 5 minutes to search through 5000 pages"…
Beyond the fact that it's single-threaded, there's an issue that has remained mysterious for 11 years (possibly more): "Why is TextOutputDev slow?"
Today I profiled the hell out of it.
Result: it's #LCMS2 ❓
Why is color management involved?! 🤯https://gitlab.freedesktop.org/poppler/poppler/-/issues/1472
