I would agree to the below sentiment for only long CPU intensive processes.
But for many normal processes, taking into consideration I/O, memory, and
having to battle other processes, more CPU's will accelerate the process.
I/O can now be handled by another CPU, and system housekeeping, etc. Of
course, you will not see 1 cpu 100%, 2 cpu 50%, etc. type of speed up as I
would interpret what is said below, but you should see some improvement, and
depending upon your workload that improvement can be substantial.

You should see an immediate improvement  .......

HOWEVER, if you are trying to reduce the time it takes to complete that
lengthy stand-alone batch job that runs every night, you will be
disappointed to discover that there will be absolutely no reduction in
elapsed time after your upgrade.

A single process can utilize only a single CPU at a given time - no matter
how many CPU's are embedded in the same box.
