GStreamer itself needs at least 0.5 seconds, on older CPUs easily > 2
seconds to initialize when the application is started.
Everything else runs instantly (meaning < 0.1 seconds) - at least on my
box. So either your measurements are way off, your CPU is way slow or
something is screwed up on your box.
