- .SH "DG/UX 5.4 DIFFERENCES"
- The WCPU and SIZE columns are not shown, nor is the "last pid" display, as
- this information is not available from the kernel.
- A "processor utilization" column is added, with the heading C. This number
- reflects a process' relative interactivity, represented by an integer from
- 0 to 7. A process with 7 is highly interactive. A process with 0 is not
- considered interactive, but uses mostly CPU resources.
- The "nice" processor time is not shown, but a "io_wait" processor state is
- added, represented the time spent waiting on I/O operations. This is
- currently always set to zero.
-
- Process are considered "idle" unless they are in "run" or "wait" state.
- Process are considered to be "system" processes if they have uid=0 and
- ppid=1.
- Percent CPU is not maintained by the kernel, and has to be calculated by
- top, by dividing the difference in system+user time by the delay period.
-
- The DG/UX 5.4 port was written by Mike Williams <mike@inform.co.nz>.
