A simple `cat /dev/zero > /dev/null' produces 100% load. Are you using a threaded program together with Irix mode? Please type in `I' during running top and see if the CPU usage is the overall or the specific CPU usage. To switch into SMP mode type in `1' during using top. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=288552#c6 --- Comment #6 from Ladislav Michnovič 2007-07-02 06:02:28 MST --- It seems that top is running in "Irix mode on" by default. I don't know if mksquashfs is threaded. Probably yes. I'm just creating LiveDVD with kiwi system. I'll make another screenshots. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=288552#c7 --- Comment #7 from Ladislav Michnovič 2007-07-02 06:15:58 MST --- When I do `cat /dev/zero > /dev/null' and checking the "top" output with Irix mode on, top shows 99% CPU utilisation. When Irix mode off, it shows only 49% CPU utilisation. Attaching screenshots. I assume mksqashfs must be a threaded program. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
