Hi... As I am now on 2.6.0-test7 using the new radeon driver I realized that the scrolling speed in a multi-gnome-terminal is approx. 8 times slower than with 2.4.
to test I used just time find ./ in my home directory and it took real 4m29.802s user 0m1.230s sys 0m7.830s on 2.4.23 something and real 32m51.384s user 0m3.884s sys 0m22.022s on 2.6. also the system load was noticably higher in 2.6 (the sysload applet was completely filled while it was maybe 1/3 filled in 2.4) Who knows the cause ? Soeren.
