Actually, most likely DAGMan isn't doing *anything* during those five
minutes -- it probably hasn't actually started running yet.  (What does
condor_q say for the status?  "I" means idle.)

What version of condor are you running?  There was a bug that often caused
scheduler universe jobs to sit around for five minutes before running, but
I'm pretty sure it was fixed some time during the 6.7 series.

Try doing a condor_reschedule immediately after you submit the DAG.
