That's not quite accurate. CFMX Standard (Professional) will use more than
one CPU if available.
Here I tested ColdFusion Standard with a smp dual proc machine running RH9
and an smp kernel. My test was simply holding down the F5 key for about 20
seconds while running top to monitor CPU. In the captured output, you see
the cfusion process using 99.9 CPU and the CPU0 shows 97% for user
processes, and CPU1 shows 98%.

---------------------------
As far as license use of CFMX Standard on multi processor machines, here
what I get out of the license agreement (you know, those 15 screens that we
all whip through when installing)
Section 1 Definitions, part (d) and (j) read as follows regarding CPU-based
and Server-based software:
------- Definitions -------------
(d) "CPU-Based Software" means, if applicable, a Software (including,
but not limited to, Macromedia Flash Remoting software, Macromedia JRun, and
the Enterprise Edition of Macromedia ColdFusion software that is not CFMX
6.1 Enterprise Update) that is not a Server-Based Software.
(j) "Server-Based Software" means, if applicable, Macromedia Flash
Communication Server software, CFMX 6.1 Enterprise Update, or the Standard
Edition of Macromedia ColdFusion software.
---------------------------------
Section 3 License Restrictions reads as follows:
------ License Restrictions -----
(o) If and only if the Software is a CFMX 6.1 Enterprise Update or a
Standard Edition of the Macromedia ColdFusion software : You may not
install the Software on a computer with more than eight (8) CPUs unless you
purchase additional licenses to the Software such that the aggregate number
of such licenses you have purchased for such installation is equal to, or
greater than, the quotient (rounded up to the nearest whole number) obtained
by dividing by eight (8) the number of CPUs for such server in which the
Software is installed.
---------------------------------
>From these definitions and restrictions, it appears to me that you are
legally permitted to use CFMX 6.1 Standard on machines having up to 8 CPUs.
Regardless of the license, the server will take advantage of multi CPU's as
demonstrated earlier.
