That is a much different result than Kris Kennaway got on a dual-dual  
Opteron system, as well as my results on a 3.2 GHz P4.  Can you  
please provide details on what version of the jemalloc patch you  
used, which MALLOC_OPTIONS flags you used, what parameters you  
specified to super-smack, etc.?

A Pentium-D should behave similarly to two single-core CPUs, right?

Thanks,
