Hello rooter ;)

When using the treeviewer to perform an analysis, I realized that xfree86 was
consuming quite a lot of CPU resources when reading the tree entries. A rapid
bench tells me that during that operation, xfree uses approximately a third
of what root requires at the same time (making it 25% for xfree and 75% for
root of available ressources) on my PentiumIII/1100/Linux(DebianWoody). 
Naturally this is a bit annoying and one would expect to leave most of the 
CPU power to the running analysis. I was wondering if the red progress bar at 
the bottom of the tree viewer was not responsible of that important resource 
consumption, maybe too much calls to X to refresh the screen.
Do you think this could be an possible interpretation ? And is there
anything, you know we can do to enhence the question ?
I justed wanted to point out that fact
Thanks for your remarks.
Vincent

PS:
