Hello, On the CPU row of top, there's various stuff displayed: 'us' (which I assume is CPU cycles consumed by processes owned by the user running top), 'sy' (which I assume is those owned by root), 'id' (which I assume means idle), and there is 'wa', 'hi', 'si' whose meaning I don't know. I checked on the manpage without success... Could anyone tell me what these last 3 (wa, hi, si) mean. Thanks...
