Is the system SMP capable?

Is the system SMP capable?

We have an appliance for which we supplied the hardware and the vendor
supplied the application (including OS). It is based off of RHEL 3
though. The vendor compiled their own kernel though (removing unneeded
things).

Is there a way to determine if the OS will take advantage of additional
CPUs if one was installed without having the kernel config file and
nothing apparent being displayed at boot/via uname? We don't want to buy
additional CPUs for the box and find out the OS will not support them.

Is there any performance gain from 2 CPUs when the OS isn't SMP enabled?

We could ask the vendor, but they are trying to push a "high
performance" appliance (software + hardware) as the solution. Licensing
is per box install, not per CPU so that shouldn't be an issue either.

Thanks
Benji
