I would agree with what Kevin said about the differences in FSB
contributing to the difference. I think you should also reconsider your
"benchmark" to the time it takes to complete two units instead of just
one. I think with 2 seti clients running on the BP6 the SMP benefit
will become more obvious.

Also, I believe another tuning trick with Seti is disable video and bios
caching which will free more cache for seti. The last trick is run cas2
if your system will support it.
