	Split calculates the percentage of elapsed clock time wasted since
boot due to split disk I/O's and window turns.  This calculation is possible
since VMS keeps track of the number of window turns and split I/O's since
boot.  Using this info and guesstimating an average disk seek time of
30 milleseconds, we can calculate the percentage of wasted time due to
disk fragmentation.

	I run split in my login.com so that I can keep track of fragmentation
on our systems.  I have seen this exceed 20% from time to time!!!  This is
powerful ammunition in justifying a defragmenter.
