Re: 10.x performance issue?

A lot of X is already stood up by the time the X "weave" background is running.

Maybe do a test by having the X server start and just display an xterm
instead of another X app?
It could be a bunch of stuff hiding in the X init shell script path
that's doing "stuff" as part
of the X env setup before a window manager is run. (and .. honestly it
could even be something
stupid like DNS..)
