Hiya. I'm looking for a tool which displays which processes (or threads) are consuming what proportion of I/O across devices, much like how "top" displays which process are consuming what proportion of CPU or memory. By I/O I mean disk thrashing, network usage, printer, anything that's a "file" really, but disk drives are a priority. Aggregate statistics aren't so hard to come by, but how do I get a per-process breakdown?
