How can this be?! - Music even stops playing for a second w/ such performance. I do not remember such behavior on old PCs w/ IDE HDDs! Or laptop is good just for reading emails today?!

In case I got it right, I have manually to renice the priority - is it correct? Or in the system is a mechanism that triggers for, auto renice writing priorities?
