It's the exact opposite: when a process is "waiting for IO" (for example in a select() ) that process is put on bottom of the scheduler table and isn't run until something change (IO or signal). Thus wait-for-IO is idle time instead than running the process, and this idle time should be justified: thus the "waiting for IO" field. There is also another fact about a process running in real-mode (AIX has a double priority queue for scheduling processes: one is normal unix mode and the other is real-mode. You can nice a process to run in real-time, and the other processes will be scheduled during wait-for-IO: no idle) Fabrizio -- | [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] | Pluto Leader - Debian Developer & Happy Debian 1.3.1 User - vi-holic | 6F7267F5 fingerprint 57 16 C4 ED C9 86 40 7B 1A 69 A1 66 EC FB D2 5E > Just because Red Hat do it doesn't mean it's a good idea.
