CPU usage of several processes increase when System Load Indicator is running

FYI: please take a look at https://bugs.launchpad.net/ubuntu/+source/indicator-appmenu/+bug/998759

I can confirm this strange behaviour with fresh 64 Bit 12.04 on a Phenom X4 with $HOME on NFS. Actually, I only stumbled over the hud-service CPU usage via constant network load of around 800 KB/sec.

That network load corresponds to NFS traffic, hence I conclude hud-service is scrapping around in $HOME. And the increased compiz load ... well, at least some load is explicable via the drawing that the indicator does. It just seems to be quite demanding drawing.

Also, increasing the update interval nicely scales down the network traffic. Is the monitoring done via a set of temporary files in $HOME that are constantly written and read? I'm tempted to say something impolite here, trying not to.

Coming back to hud-service: I assume it is constantly aroused by business in $HOME? Come on, eh ... here is the temptation to utter something impolite again. I hope this is resolved quickly, and integrated into the LTS. Lots of work to do till this year's LTS can be considered stable ... (damn, tried to be nice)

I see the relation to bug 998759 now. That nicely explains my observation; well, at least moves the burning question to a lower level.
