profiling file of 3 programs making xorg excessive cpu usage

I am using linux ubuntu lucid on amd64 athlon xp 3200+ cpu with asus k8v-se motherboard, nvidia fx5200 graphic adapter, 1,5Gb ram

When i launch some page on firefox3 like this one http://www.europalms.be/ i can see Xorg taking 80% of the cpu, about 40% to 70% with audacity last version and sun virtualbox reach 30% to 40% on xorg depending the cases.

i attached the profiling files for 3 of them.

I can tell it is not coming from the graphic driver because i tryed as well on Nvidia legacy 173 and "nouveau" with the same results.

It is a new problem i could find a lot of occurence from 3 years on the past which looks like have not really been resolved.

I am at your disposition for further tests or logs

Thanks and best regards

I'm not sure what profiling tool this was from, but it appears to contain very little information about what Xorg was doing.
