Looks like you need a two plans of action: 1) figure out why it is taking 2 seconds loading: profile the loading and propose patches to Qt. 2) implement the kdeinit / booster trick. I'm not sure there's a good reference online, but here's a very, very summarised summary: - all applications become plugins instead - there is only one central application - the central application links to Qt but does not *use* anything (no QCoreApplicaiton, no QApplication, no QFile, no QObject, no QString) - the central application starts and listens for requests - each requests tells it what to plugin to start, by: a) fork b) dlopen c) call a main()-like function -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
