The only GUI processes running are an XFCE desktop, Thunderbird, Firefox and xload. As you can see the number of context switches triggered by the firefox and Xorg processes is excessive. I assume this is what is causing the higher than expected CPU load. # (cd /proc && for p in [0-9]*; do echo "$(grep ^voluntary_ctxt_switches $p/status | { read a b; echo $b; }) $p $(read a b https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
