The project I am working on had the same problem after upgrading from GTK+ 2.1 to 2.12 on Solaris 9. Even a hello-world app was taking several seconds to open. So, I profiled hello-world and found that most of the time was spent on font rendering. Newer versions of GTK+ are now using fontconfig and cairo for font rendering. So, we deleted some of the useless fonts and ran fc-cache to cache the fonts for fontconfig. Our apps are starting up much faster now. While we are on the performance subject, our apps are still a little sluggish with screen updates since upgrading to 2.12. We could be wrong, but we are guessing that switching to the new cairo has moved a lot of processing from the cpu to the graphics card using XRender extensions. Our project is stuck using old Solaris machines (Sunblade 2500) with old graphics cards (XVR-1200), and the graphics card may not support the render extensions. Does anybody know of any ways to tweak GTK+, X, Solaris, or the graphics card to make our apps as fast as they were in GTK+ 2.1? Also, could anyone clarify our assumptions about GTK+ changes from 2.1 to 2.12 that could impact performance?
