now i'm wondering, using the same parallel algorithm which one would  
perform better? a 1 cpu quadcore machine or 4 cpu single core machine?

most of my j system running on the server are still on a 4 cpu intel  
xeons. most of the new deployments are using the multi-core units.

i am under the impression that the single core multi cpu (4 cpu X  
single core) setup is faster than the multi-core multi-cpu (2 cpu X  
quad core)
but I have no metrics to back this up. just an impression.

am i right or just batty as usual?
