The following is a demonstration of the bottom program,


Here we run bottom. By default it will update the screen every 5 seconds,
printing the bottom processes by CPU usage,

   $ bottom

Now we know which processes are using the least amount of CPU.


It's likely to be useful to run the regular Solaris "prstat" in one window,
and "bottom" in a window below it; that way you are seeing both top and
bottom processes.
