I'll check if I can reproduce this here.
I can't with kvm. Here it takes around 8s to start gimp repeatedly with the same kvm config - both installed gnome live cds (they call it ubuntu though :). I get ~21000 relocations on openSUSE and ~17000 on ubuntu, which is an indicator that they have less libraries and/or modules. But once they are in cache, the shouldn't make a difference. And especially not as large as you measured it. How much memory did you give your installs btw? And cold starts shows a significant difference. Dropping caches and loading gimp on ubuntu takes ~11s and loads 21MB from hard drive. On openSUSE it loads 46MB and takes 15s. Now let's see what's the difference in files loaded. If we only check the top 10 files: Ubuntu: 1012 /usr/bin/gimp-2.6 281 /usr/lib/libgimpwidgets-2.0.so.0.600.6 138 /usr/lib/libIlmImf.so.6.0.0 110 /usr/lib/libgtk-x11-2.0.so.0.1600.1 72 /usr/lib/libgegl-0.0.so.0.22.0 65 /root/.gimp-2.6/pluginrc 52 /usr/lib/libgimp-2.0.so.0.600.6 51 /usr/lib/libSDL-1.2.so.0.11.2 50 /usr/lib/liblcms.so.1.0.18 46 /usr/lib/libstdc openSUSE: 1915 /usr/share/icons/Tango/icon-theme.cache 1038 /usr/bin/gimp-2.6 800 /usr/share/icons/gnome/icon-theme.cache 675 /usr/share/icons/hicolor/icon-theme.cache 288 /usr/lib/libgimpwidgets-2.0.so.0.600.6 165 /usr/share/X11/locale/en_US.UTF-8/Compose 145 /usr/lib/libIlmImf.so.6.0.0 108 /usr/share/fonts/truetype/DejaVuSans-Oblique.ttf 108 /usr/lib/libgtk-x11-2.0.so.0.1600.1 103 /usr/lib/libopenraw.so.1.5.2 So yes, our gimp links against libopenraw (410K) and uses Compose by default (700K), but the main difference between ubuntu and openSUSE when it comes to GNOME applications in general: We have way more icons and love to read the cache. If you only count accesses to icon-theme.cache, you get 13.2MB - which does not explain the full difference but the major part of it. But there is a catch: these icon themes are supposed to speed things up when they are in cache. And they will very likely for GNOME users. But it's likely the reason of firefox being slow to start under KDE.
