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.
Well, by default the MIT-SHM extension is compiled for XFree86. Also if you haven't been following the XFree86 development lately major changes are coming especially for XFree86 5.0 =) Check out http://www.xfree86.or/~keithp/talks Lots of good new extensions being added. In the current cvs snapshots you can now change the mouse cursor and ge shadowing like XP. -ShawnX
