I was doing some testing with DBT-3 on our 8-way STP systems and
noticed a significant difference in the execution of Query 2 using
8.0beta3.
Here is the query template we're using:
select s_acctbal, s_name, n_name, p_partkey, p_mfgr, s_address, s_phone,
s_comment
from part, supplier,

The plans are different and I suspect thats where the differences lie.
For brevity (and readability) I won't copy the plans here but I'll
provide the links. Search for 'PERF1.POWER.Q2' in the file, it's the
second query executed and you'll notice the differences under the
SubPlan:
