[htop-general] CPU% question (without attachment)

PDF not attached ...


Greetings,

I'm trying to use htop to monitor CPU usage of various processes, but I'm 
having trouble understanding what exactly the CPU% column is telling me.  I'm 
running on a 4 CPU Redhat EL4 (2.6) machine.  I've attached a PDF of the screen 
in question, but it might not make it through the mailer.  The top of the 
display shows the 4 CPUs with percentages of 48.4%, 44.4%, 40.0%, and 40.3%. If 
I total up the CPU% column, I get 687.2%.  The first three processes show 
87.7%, 84.8%, and 80.3%.  Can someone please explain what the CPU% column is 
telling me here?  I'm totally confused.

Also, I've found that switching from machine to machine can cause a problem 
with the number of CPUs displayed at the top.  htop remembers the number of 
CPUs from the last time it was run.  I had to alias htop to "/bin/rm 
$HOME/.htoprc; htop".

Thanks in advance for any help.
