Any one (non-threaded) process can only run on one CPU at a time. As
Netscape is a single, non-threaded process it will only ever make use
of one processor (at a time).
This doesn't mean you don't win from having a multi-cpu machine. On a
single CPU box you might find that Netscape gets 80% of your CPU, whilst
everything else is using 20%. On a dual CPU machine, the other processes
will move to the other CPU, and Netscape will be able to peak up to
100% of a CPU - only a little gain, but better than nothing.
The real benefit of multi-proc machines is when you're running multiple
CPU intensive processes, or when you're running multi-threaded processes.
