        I have experienced going from 12 Cpu SMP to 4 CPU Numa and 4 was better though much of the improvement was most likely due to the fact we also replaced the disk farm from 150 small disks to 16 disks in an EMC unit. On the old system 2.5 hours to rebuild one index. On the new system 15 minutes.

Interesting. A 10x improvement. It seems reducing your physical platters by 90%
would get you that. Could it me that there is actually a dramatic reduction in
physical I/O ?

What is a 4 CPU Numa BTW?
