Both X servers came from the same original code base, and Xorg is now
Sun's X server, getting the work to be made stable, faster, and better
integrated.

Not for any graphics cards made recently. I don't remember finding
a single card in our testing in which Xsun was faster than Xorg. The
years of undersupporting it when Solaris x86 was declared "for servers"
and then "indefinitely delayed" cost Xsun's x86 driver support - only
enough to support new cards was added, not to accelerate them.
Most people even use drivers from the same sources now, when they choose
the "XF86" drivers in kdmconfig, which are the Xorg drivers using the
XFree86 Porting Kit layer (which adds another layer and thus some speed
loss). The S10U2 Release Notes should include an End of Support warning
that the older non-XF86 drivers for Xsun are not likely to be included
in the next full (non-update) release of Solaris.
