You should see it do this with an uninstalled GStreamer on my slow-ass
laptop HD :) 1 minute is not unheard of.

Ronald, 10 s - is this uninstalled or installed ? You should time the
startup of that, I'm going to put money on most time being spent in disk

Some people discussed the idea of making the registry emit signals while
loading plug-ins, to enable gimp-style loading dialogs, but most people
hated the idea and prefer to work on speeding up the load instead.

Precisely to address the issue of gst-register being required to run.
Now that any app can rebuild the registry (but it takes a little time to
do so), the need for a specialized binary for this task is gone.

However, if startup time on the first run of any gstreamer app after
installing a plugin is an issue, distributors can choose to trigger a
registry rebuild by running any gstreamer binary.  gst-inspect then
makes the most sense.

So Tim meant to say what you said - the fact that it was required to run
it caused the most problems.  I hope people are happy that that's gone,
not angry :)
