Something is wrong somewhere if doubling > your CPU's results in a factor of 12 slowdown surely? Is it possible to disable one of the quad-core cpu's from bios?

If so it could be interesting to see whether the specific task goes slower/faster. -- regards Claus When lenity and cruelty play for a kingdom, the gentlest gamester is the soonest winner. Shakespeare
