If I am watching a Netflix movie, I wouldn't want some batch file download to interrupt me, because, obviously, the response from an interactive process is expected with higher urgency, compared to a batch result. Assuming that disk/network IO is a bottleneck, is there a way to prioritize them based on pid? Yuri
