New Computer Program Doubles Sorting Speed - Again

SANTA BARBARA, CALIFORNIA -- Robert Ramey Software Development announced
version 2.23 of the Postman's Sort. This version uses 32 bit instructions
to run twice as fast as previous versions.

The Postman's Sort has recently been incorporated into the Flagship product
of a major SQL vendor. Response to SQL queries requiring sorting are TEN
times faster than with the previous system.

One customer reported the following results when sorting a 100,000 record
file consisting of 15 byte records.

Psort386   18 seconds
Psort      56 seconds
Foxpro     95 seconds
Clipper   313 seconds
Dbase     504 seconds

The test was conducted on an PC compatible with a '486 running at 33
Megahertz with no disk caching enabled.

Sorting is the ordering of records within a file by date, name, zip code,
account or some other piece of data. It is used by almost all commercial
applications such as preparing bank statements, accounting reports,
mailing lists, phone books, etc. and is an integral part of all data base
systems.

The program is called the Postman's Sort because it uses a method of
sorting records similar to that used by post offices. Until now, computer
sorting has been done by comparing records two at a time. The time
required to sort records increased disproportionately to the number of
records to be sorted. For most files, the time required to sort records
using the Postman Sort is strictly proportional to tho number of records
in the file.
