Please LEARN something about what you're talking about before you shoot off
your mouth.
There is NOTHING from 'xdyinfo' that can identify XFree86, or any other
MIT-derived server. If 'xdypinfo' shows the same vendor string as XFree86,
that's because neither XFree86 nor MetroLink decided to change the stock
MIT vendor strings.
The reason that XFree86 is so much faster than the MetroLink server is that
the two are almost COMPLETELY INDEPENDENT of each other. And MetroLink
hasn't incorporated Glenn Lai's SpeedUp code, which we have.
And - guess what - MIT hasn't written EITHER server, at the level you're
talking about. Or it could be said that MIT has written just about every
X server out there.
You will find FAR more similarities between XFree86 and the SGCS server
than between XFree86 and the MetroLink server. There's a good reason for
that. Both XFree86 and the SGCS server are derived from Thomas Roell's
excellent X386 1.2 server, which was part of X11R5.
Take it from someone who knows - you have NO IDEA what you are talking
about.
