I'm not sure I understand myself. I stopped it while scrolling and copied
the first few lines below:
Tasks: 126 total, 2 running, 124 sleeping, 0 stopped, 0 zombie
Cpu(s): 49.9%us, 4.8%sy, 0.0%ni, 45.1%id, 0.2%wa, 0.0%hi, 0.0%si,
0.0%st
You have the (1) toggle on so that all CPUs are aggregated into Cpu(s).
Turn off the toggle to get a separate line for each CPU. According to
this your system is idle about half the time. I suspect that one
processor (the one running Xorg) is going flat out and the other is
idle. I don't know if Xorg is multi-threaded and able to run on
multiple CPUs or single threaded where SMP doesn't help. Hopefully, the
application can use the other CPU to spread the load.

If you have Irix mode set, then Xorg is using 100% of the CPU on which
it is running. If you have Solaris mode set, then Xorg is using 100% of
all CPUs, for the time period since the last refresh.
Doug.
Thanks. I also found the threads option (H) in the man page. Below is a more
complete top listing, with (1) and Irix mode off, and threads on. It shows only
about one third of the total number of tasks.
