Hi!
This is simple cat /dev/sda > /dev/zero... on thinkpad x60 (x86-32), with spinning rust.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1000 root 20 0 0 0 0 R 53.3 0.0 57:34.93 kswapd0 27897 root 20 0 6976 580 536 R 44.5 0.0 1:44.53 cat
It keeps both CPUs busy... and I don't think that's right.
