I've noticed a few webpages to trigger lot of X11 related network traffic just by watching them even without any seeable content change, but CPU load on browser and especialy X process went high, but of course symptoms might be different with different drivers - I use mga myself. I never analysed it properly beacuse I'm using a quite old Xorg version, but I see the increase of traffic on the domain socket. I also noticed that recent firefox and seamonkey are doing lots of NFS traffic, so I was forced to switch ~/.mozilla to a local disk, where iostat still stays idle. But my OS is also not very recent, so I also never debugged this problem. > Run top in the mode where all system threads are shown separately > (e.g. top -HS seems to do it), then watch what thread eats the processor. -- B.Walter <bernd_at_bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.Received on Sun Jul 18 2010 - 08:19:36 UTC
