And that's just for command line programs. GUI programs packages as snaps have much greater startup costs. It takes the Ubuntu calculator 4-5 seconds to launch.

And that's just for command line programs. GUI programs packages as snaps have much greater startup costs. It takes the Ubuntu calculator 4-5 seconds to launch. It takes Mumble 12 seconds to launch. The latter launches in 2 seconds as a native package, and the former, well, is a calculator app - I don't have access to a non-snap version of the Ubuntu calculator anymore but is should launch virtually instantly.
