I think that piling up different problems into a single discussion, even if they involve a common component (to a certain degree), is not going to help anybody. If I have read this thread correctly (and taking the subject line as a witness) the OP had a problem with heavy I/O activity screwing up interactivity. I think that it's not the same problem as sub-optimal performance of heavy CPU-bound load, which is what you reported if I am not mistaken. -- Andriy Gapon
