OSDL DBT-2 AS vs. Deadline 2.6.0-test5-mm4

[markw]

DBT-2 is an on-line transaction processing (OLTP) workload, a fair use
implementation of the TPC-C.

Results between the two elevators differ by about 4.5%, with the AS
elevator having the edge this time.  Results between the AS and deadline
elevator are still pretty close.  I don't believe results have changed
dramatically since 2.6.0-test5-mm3 and I don't see any significant
changes in the profile, so things are still looking ok.
