I remember I needed some quick changes to a very large PS dataset, and
not wanting to struggle with DFSORT syntax I wrote a quick assembler
program (QSAM with a large block size and extra buffers). Nothing could
be faster than an assembled program, right? Later I figured out how to
do the same work with DFSORT or ICETOOL, and was surprised when the SORT
job ran in about 25% less clock time than my own simple program. All I
could guess is that DFSORT has some DASD tricks to speed things up, like
you say.

Without wishing to appear a "die hard defender of DFSORT" :-) I would
expect DFSORT's I/O speed to be better than that of a program (even with
decent Sequential File tuning). But that quite possibly DOESN'T matter.
