Being a BeOS user (a purely desktop system) and because I code under Linux, I see XFree86 (v4.1 on my machine) as a user and as a developper. And this is where the problem lies. My Gnome or KDE desktops are slow in comparison with other operating systems, but XFree86, the 'engine' behind these desktops, proves me that it's not. Let's look at what I have in front of me: a dual Pentium III at 933Mhz with 512MB of memory, a Radeon 32 AIW, a modified Mandrake 8.0 powered by kernel 2.4.18.

The Radeon drivers he has are extremely poor. My x11perf numbers (nvidia driver) are anywhere from 3x (in the case of filled rectangle and putimage) to 10x (in the case of lines) as what he shows. Previous benchmarks I've done against Windows 2000 show that these totally blow away the GDI (especially line performance) while the blit performance easily matches DirectDraw 7.
