processing speed, optimizations for AMD Opteron


does know if analysis services has binaries optimized amd opteron? reason ask seeing dramatic performance difference between 2 systems:

system: dual xeon irwingdale 3.4 ghz, chipset e7525, 4gb ram
os: windows xp pro sp2
fact rows: 20,000,000
aggregations: 1300
processing time: 3 hrs

system: dual amd opteron 246 (2.0 ghz), amd chipset 8000 (mb tyan s2885). 4 gb ram
os: windows 2003 enterprise (sp1)
fact rows: 20,000,000 (same data set 1st case)
aggregations: 1300
processing time: 6-7 hrs

both test environments have the:
same ram speed
same model hdds


is difference due lack of amd-specific optimizations in ssas binaries? or other reason?


also there way reduce thread priority on ssas binary during optimization? seems hose machine (windows 2003 ent.) during processing. when attempted change processing priority through task manager got access denier error (logged in admin)

did test under same os , 100% equial options?

such difference have acounted seems screwy.
