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.
Guillaume,
On the B.E.OS website I read that windows in 'normal mode' are drawn into a shared buffer and blitted to the framebuffer instead of drawing directly to the screen.
This, of course, improves performance.. like said on your site.
But why don't you submit this back to the XFree project so that everyone can enjoy better performance?
(and it would be even more cool if those buffered windows could be drawn during the vertical synchronisation
Just wondering...
