(Potentially) Speed Up Application Launch Times on Linux
To (potentially) speed up launch times for Qt, KDE and Gtk applications, make a
.compose-cache directory in your home folder:
mkdir -p ~/.compose-cache
I know that sounds like voodoo, but see the
Compose man page, and this post at Rob’s KDE Blog for an explanation of why this might have a noticeable impact, depending on the applications in question, your distribution, hardware, &c..
Update: @andrewheiss reports that this ‘works for Gtk/X11 stuff on OSX as well’.
