Hello,
Scriu si eu cam cu aceeasi nelamurire.

What's going on? Unde e?
El pare ca foloseste ambele procesoare logice:
USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND
root 11 99.0 0.0 0 8 ?? RL 2Feb06 14600:27.52 [idle: cpu1]
root 12 99.0 0.0 0 8 ?? RL 2Feb06 14618:40.02 [idle: cpu0]
La un `openssl speed` incepe sa rontaie doar din cpu1 (cam 99%, nu-l
incepe deloc pe CPU1). Daca ii mai dau ceva de facut incepe sa
rontaie si din cpu0. E un comportament normal?
