Actually the window in which I run top only refreshes when the CPU is not maxed out. I'm trying to find a way of logging to a file the CPU activity but it all seems to me that the X process if eating all the CPU cycles.

before changing anything, when moving windows, top shows:
70-75% to X about 10% to metacity about 10% to gnome-terminal
when idle, top shows: <2% to X <2% to gnome-terminal <1% to other applications
after changing:
<<Replace [...] videoRam line with Option "BackingStore" "On">>
top shows:
about 50-60% to X about 10% to metacity about 10% to gnome-terminal
(a little better, thanks, although I can still see the screen redrawing)
Does this tell you anything? Can this be made batter? This is still quite slower that it used to be in ms widows.
Things I noticed:
1 - in XFree86.0.log the: (WW) ATI(0): Cannot shadow an accelerated frame buffer. has been replaced by (II) ATI(0): Using shadow frame buffer.
2 - (WW) ATI(0): Extraneous XF86Config VertRefresh specification(s) ignored.
is still there
3 - instead of (==) ATI(0): Backing store disabled I get (==) ATI(0): Backing store enabled
Thanks a lot, Salvio

CPU is idle - CPU is maxed out when moving windows
swap memory is not used
less than 50% of available phisical memory is used
(both when moving and when not moving windows)
You've said that already. But which process(es) is(are) eating CPU? The
xterm, the Xserver, or some combination of both?
Is this a 3D app?
No.
This happens with all X applcations.
I'm testing using two XTerm windows and an empty desktop.
OK.
what is the meaning of this?
<<see if turning on backing store has any effect>>
Replace your XF86Config's videoRam line with Option "BackingStore" "On".
