I don't have Xubuntu myself (I've just installed & maintain it for
relatives), so I cannot test now how much exactly each of the CPU
utilization applets takes by default, but at least you can change
their update intervals to something more sensible than their default
interval.
If I remember correctly, the CPU graph updates take ~1% of CPU
on 1.4Ghz AMD Athlon XP, when the updates happen at 1Hz interval.
I just don't understand why their max interval is limited to about
1 sec. On older machine even a bit longer interval would be nice.

CPU utilization applets (was: Panels in Oneiric Ocelot)
Hello,
I experience the same problem with the CPU (and memory) usage
indicator on Xubuntu. I had a look at the code and found a number of
efficiency savings that could go into it. For instance, you need not
rewrite the bars every quarter second, maybe just if they change by
more than, say, a 5-10%. And there are some calculations inside the C
code that could be done otherwise in order to improve performance.
I tried to contact the developer, but he never answered back, though.
Best regards,
Carlos J. Gil Bellosta

Please start a completely new subject. We now have so many discussions
in this thread it is fast becoming useless. If the simple panel
discussion thread has to be used for every discussion of an issue, I
will disregard the entire thread and nothing will be used from it.
If you do not use a proper threading email client, it would be good to
find out what that is.
