What gfx driver are you using under XWindows? The "XWindows graphics" one or
the DGA one? The first is always slower, and it's normal as it uses the XWindow
protocol (that also allows to run a program on a remote computer and see the
output on your local screen). The DGA driver is surely faster, and it should
not differ so much in performances from the svgalib one...
What version of XFree86 are you using? If you're using 4.0.x, you could try out
the current Allegro CVS version, as I just recently added to it a new DGA 2.0
driver that also uses hardware acceleration if available. Speed should not be
a problem anymore... =)

Well, I guess I belong into the group of people who confuse days with
months and so on :-) I retried the example, and it now works correctly.
Maybe the test I did was with that mmx version of blit which was wrong
around 3.9.31/3.

Anyway, now everything seems to be working all right (and I deleted one
more of my pending emails. Hey! I hope to reach soon that fbcon patch :-)
