Anyone please???? SMP health check!!

[vizion communication]

Thanks very much for your comments -- they are really
appreciated.

OK is there any way I can check that SMP is performing
properly??

I do not seem to be showing an increase in performance
between single and smp processing.

What issues would not be revealed in Dmesg?
