on intel cpu`s spamfilter uses rtutils.dll and runs more smooth,on amd cpu`s spamfilter spikes very ugly.(not calling this dll from the kernel) why is that ?

we are testing an new amd server (aka appro) and spamfilter behaves really bad.

stack from process explorer :

SpamFilterSvc.exe+0x582a0
SpamFilterSvc.exe+0x77f0e
kernel32.dll!TerminateThread+0x113

No rtutils.dll, all other mdac/adc calls are made well, please note that it runs well, but spikes to much 2-20% cpu every 5 seconds, i noted this on an older athlon 1ghz another athlon barton, and now on the newer ones too...
