Jesus Christ, Zanshin. Don't shoot the messenger! Sorry to rain on our Pacific parade, I am just calling the attention of like-minded users to a CPU usage that is indeed very high. I've said it and I am done, no use arguing about this, especially if you insist on contradicting my measurement without carrying out yours. I wouldn't still be here if you stopped calling me back.
Also I don't know how it is not a problem for a string quintet to consume 5 cores. Please teach me how to download more cores, evidently I need them.
By the way, nothing wrong with AMD CPUs, mkay?
