True...The problem may be someplace other than IO.  The same large dataset
is read by Proc SQL in a different job and that step takes a bit more than 2
hours to run.  The SQL is a simple count with group-by on 7 fields; it
returns about 1 record for every 1000 input records.  I don't know if basic
IO and SQL IO are radically different.

I have some stats from a run with no bufno and with bufno=100.  There is no
significant difference between them.  I've started another run with
bufno=1000 and with OBS=half-the-file.  I'll post all the results this
afternoon.
