Ah, OK, never new that. Thanks for the correction!

1. Generally the ID you mention is called the PID, to distinguish it from the
UID or GID or PPID.
2. The Percent of CPU is percentage of a single processor. It is calculated by
dividing the CPU used by a process by the time change since when the CPU was
last checked, or the Process Start time. It can be greater then 100 percent if
two conditions are met.
1. If your computer has multiple processors or cores.
2. The process has multiple threads. A thread is one way for a computer
program to divide a task into distinct tasks. Voice Over probably has one
thread for speech output one thread for receiving keyboard input , one thread
for understanding a windows elements.

If you're talking about the number at the start of the table (like 106, 160,
240, etc) it's no the cpu usage. It's the id of the process
Nothing can use 106% of your cpu.

I would expect that Voice Over is very sluggish for you. Usually when
something is between 93-110 percent CPU I have found that one of the threads
of the process is in what computer scientists call Infinite Loop. Yes, I know
that Apple HQ is at 1 Infinite Loop, but still this is not a good thing and the
sometimes the only solution to this is a force quit or kill. My VoiceOver when
working normally is at 10-15% CPU.
Best wishes,

Hello List:
I was just looking at Activity Monitor and noticed that VoiceOver is using 106%
of my CPU. Is this normal? If not what should I do about it?
Thanks,
Doug
