Hello John,

you should increase the number of openser children to fully utilize the 
additional processing power available. The debian packages are already build 
for an SMP environment, if you compile by yourself set the variable "ISSMP" 
in Makefile.defs to yes. This will ensure that the right locking primites 
will be used, otherwise the server don't need to make any assumptions about 
the processor count. 

Likewise tune (increase) the private and shared memory settings 
(config.h/ "-m" parameter) to use all the memory available, keep in mind that 
mysql also need memory for good performance.

Cheers,

Henning
