Cache Test v 1.0
by
George Spafford

Summary

This program is designed to help a user evaluate the impacts
of a cache, or the changes to an existing cache, on a drive's
performance.

Cache Test creates 10,000 record files on a desired drive first
by a sequential method and later by a random access method.
These temporary files are approximately 1.3 megabytesin size.
This program uses BIOS to do all of its reads and writes, so
any hardware or software cache should be able to get some good
"hits."

All of the times that this program writes are the result of
subtracting the beginning time from the ending time. Nothing
fancy, so I would assume that the values are relatively accurate.

A few definitions:

"Crescendo Read" Records are read alternatingly in from the end of
the file and the beginning file. This is to say,
record 1, 10000, 2, 9999, 3, 9998, 4, 9997 etc.

"Stepping-by-1" A random access file's records are being accessed
one at a time.

"Stepping-by-10" A random access file's records are being accessed
on every 10th record.

"Write-by-10" A random access file's records are being updated
on every 10th record.


"Overall" This is the total time of all tests AND file
deletes. So, it might not reflect the sum
of all tests exactly, but it should be very
close.

I just wanted to make those meanings a little clearer.

******************************************************************

Usage of this program is:

CT

CT by itself will clear the screen and then ask you for the
desired drive and then proceed.

CT /D

This will immediately test drive D:
CT /C will test C: and so forth.

CT /?

This brings up a brief summary screen.

I hope this program helps you evaluate some of your problems
or even makes some solutions/benefits clear. I wrote this
during some of my spare time and if you would like to make a
contribution to offset some of my modem's phone bills, I'd
appreciate it ($5). If you have any suggestions, I'd REALLY like
to hear those too.

Is it just me, or do all of the disclaimers look the same??
