Yes, the reason you need finer grained locking is because the interrupts *should* go to the other processor. If one processor is handling an interrupt and annother int comes in, the other CPU should be able to handle it. This would finally give parallel I/O! Linux doesn't do this, and they do very poorly when not every process is CPU bound. Kevin ps: This will most likely mean fixing device drivers as well.
