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, Jason
