System monitor detects two processor cores instead of one.

Opensuse and Linux newbie here so go easy :). Basically system monitor and the “top” command show 2 cpu cores when I only have 1 (a 3 Ghz P4 on my work computer).

I’m not sure if the two are related but I frequently get 100% CPU usage when running a few programs together (Kile, Firefox, Chrome and okular for example) at which point even the movement of the mouse cursor slows down.

Any theories?

Thanks

If you have a processor with hyperthreading, it effectively has 2 cores.

Cheers for the reply, that should explain it. I’ll post the cpu usage conundrum in the software section (since it seems software related as I don’t have the same problem when using gnome).
