My guess is that the numbers you are seeing and probably pretty normal
(both for dagman and when calling directly from the command line).
We see faster times (real = 0m2.454s, user = 0m1.315s, ~40 jobs/s), but
have a pretty customized config. For instance, we set
SUBMIT_SKIP_FILECHECKS = False
SUBMIT_SEND_RESCHEDULE = False
I would assume that both of these knobs would reduce submit times
(although haven't tested them myself).
Also note that we are running on a 16 core Nehalem machine - so that may
influence comparative results as well.
