True, but one shop I worked in went to the other extreme:
full-track blocking for every file.  One system consisted
of a program that created half a dozen work files (even
though some were redundant).  Six output files - plus an
input file - with a track size of 10K meant that 70K of
the machine's 192K went to buffers alone.  It certainly
didn't make anything else run faster since there was no
memory left to run more.

And rather than just sorting the work files and printing
reports as successive steps, another shop standard was to
kick off separate jobs to sort and print each one.  Now
_there_ was thrashing for you - just moved to the job
scheduler.  I wrote one such system for them, and found
that the entire job would take about 20 minutes just
to schedule, let alone run.  I said to hell with their
standards, wrote it in a sane fashion, and got test runs
through in a minute or two.  They were furious, of course,
but I pointed out that they were perfectly free to change it
back to their time-consuming way once I was finished testing.
