OSDL is nearly complete with their automated tests.  Tests 
completed so far:

LTP          1-way, 2-way
contest      1-way, 2-way
reaim        1-way, 2-way, 4-way, 8-way
lmbench3     1-way, 2-way
bash-memory  1-way
iozone       1-way, 2-way
tiobench     1-way
hackbench           2-way, 4-way
dbt2 (SAP)                 4-way
dbt3 (PostgreSQL)          4-way

I have taken a quick look at the results and I see no degredations
from 2.6.6-rc2 and the performance looks much better than the 
2.6.5 kernel for dbt3 (as reported earlier).

The URL to the test results (a dashboard of info) is located here

http://www.osdl.org/projects/26lnxstblztn/results/

Click the link along the patch-2.6.6-rc3 row under a desired test
if you care to scrutinize the results further.
