Valid command-line switches for this program are as follows:

/b - bypass this initial screen
/nv - don't perform initial video test
/q - run in quiet mode (no sound)
/xx - run for 'xx' seconds, then exit


USER INTERFACE

You may control this program with a mouse and/or keyboard.
To scroll the text in this box, click on the up and down arrows in the text
box border, or press the up/down arrows, or page up/down keys.
To change the scale of the speed bars (normally yellow), click the left or
right mouse button while the mouse cursor is on top of the bar. Left button
increases the scale to make the bar shorter (violet), and right button
decreases the scale to make the bar longer (cyan, or light blue). Press F3
and F4 to increase/decrease the CPU and FPU scales, or F5 and F6 to change
the video scale.

If you are running on a monochrome system, you will not be able to discern
what CPU type or speed scales are active from a distance because color is
used for those purposes.

Press F1 for help, F9 to recalculate video speed, F10 to toggle the beeper
on and off, and Esc to exit the program.

You may run the program with one or more command line parameters separated
by spaces to affect operation:
SPEED /B - bypass initial help screen
SPEED /NV - no video (disable video test)
SPEED /Q - quiet (disable beeper)
SPEED /40 - run for 40 seconds and exit
SPEED /B /NV /Q /40 - all of the above

THE TESTS

The system speed tests tell you the most important information about the
computing performance of your system: the effective speeds of the central
processor unit (CPU), floating point unit (FPU, math coprocessor),
and video display circuitry. Although hard disk access and data transfer
rate affect system performance, we excluded those tests because they do not
affect actual computation speed.

CPU/FPU Tests

The CPU and FPU speeds show performance relative to an IBM AT with a 6 MHz
80287 math coprocessor chip installed. For example, if the display shows
CPU speed to be 22.53 MHz, it means an IBM AT would have to run at 22.53
MHz to have the same computing performance as this computer. If the display
shows FPU speed to be 40.25 MHz, it means an IBM AT would have to run
its 80287 math chip at 40.25 MHz to have the same floating point math
calculation performance. The speeds are NOT the actual CPU/FPU clock speeds.

CPU Test

The CPU test forces the processor to show the effect of instruction cache.
It is thus more accurate than previous versions. On color systems, the
background display is gold for 8088 and 8086 CPUs, green for 80286,
blue for 80386, and red for 80486. This allows you to see from a distance
what kind of CPU is running the system. The display also shows in text the
type of CPU installed.

FPU Test

The FPU test shows a value only if a math chip is installed or built into
the CPU. Where possible, it shows the manufacturer of the chip (e.g., Intel,
Cyrix, IIT). Note that the 80486 has an internal FPU, but other CPUs do not.
The test accurately reflects the higher performance of a closely coupled
CPU-to-FPU architecture.

Screen Updates

The program runs both CPU and FPU tests continually, and updates the display
about 4 times per second. The speed will drop if you run another application
concurrently or change CPU clock speed. You will be able to see the system
speed degradation caused by multitasking or background network accessing,
or by taking the sys
tem in and out of turbo mode.

Clock Speed / Multitasking

Multitasking does not affect actual CPU clock speed, but allows less time
for the speed test to run; turbo mode actually changes the CPU clock speed,
and thus affects the performance of both multitasking and the speed test.
Some systems do not have a turbo mode, but those that do usually allow you
to invoke it with a front panel switch or the keyboard (normally
Ctrl-Alt-plus or Ctrl-Alt-minus).

Variable Readings

As the test runs, you may notice the CPU and FPU MHz values changing
slightly. This does not mean your system clock is running erratically,
but rather that test results are being rounded off, and occasional
interrupts in the background are using CPU time.
If you want the fastest possible readings, you should boot DOS on the
computer with no drivers or resident programs installed. Such software can
cause the CPU to work on special tasks in the background while the speed
test runs in the foreground. The special tasks will take CPU time and cause
the speed test to give lower readings than it should.
Large temperature changes can cause PCs to vary in performance
characteristics. As a result your computer may run faster when it is cold
than when it is warmed up.

Video Test

The video test checks pure data transfer rate from the CPU into video memory.
It thus shows the maximum speed at which data can be read and displayed.
The video test detects most popular video adapter chipset types, and displays
the type and manufacturer on the screen. If it cannot determine the
manufacturer, it shows just the generic type, such as monochrome, CGA, EGA,
or VGA.

Video / System Design

The video test results are affected by video adapter design, CPU speed, and
system board design. For example, some systems have fast I/O bus speeds
and allow a fast data transfers to video adapters. Others, even some with
very fast CPU speeds, have slow I/O speeds and thus slower display rates.
Much of the power of a fast video adapter can be wasted if it is used in a
slow system. On the other hand, a slow video adapter can impede the faster
systems, giving diminished performance in display-intensive applications.

Video Runs Once

The program runs the video speed test only once, at the beginning. This is
partly for aesthetic reasons, since it makes the display look unattractive.
You may re-run the video test by pressing F9 (recalculate). You will need
to do this if you take the system in or out of turbo mode while the normal
speed test is running, because video speed can be affected by CPU speed.

Video BIOS

The video test does not show the effect of BIOS on display speed because
most popular high-performance applications write directly to video memory,
and do not use BIOS. Furthermore, most super VGA adapters come with a
program that loads display BIOS into system RAM for maximum execution speed.

SCALES

All of the test results are shown on variable scales. The default scale
values are different for each CPU type, but the default speed bar is always
yellow. This allows the program to show how the performance of your
system compares to the scale limits for your processor type.

Thus, if you view the screen from a distance, the program accurately renders
performance information without the exaggerated effect of display wrap-around
or logarithmic scaling used in earlier versions of the program. If you see a
yellow speed bar, you are seeing the default scaling for your CPU type.
If you are running on a computer that is slow for the class of CPU it uses,
the speed bars will be short. If the computer is fast, the speed bars will
be longer. If the bar is too short or too long for your liking, you may
change its length by adjusting the scale.

However, when you change the scale, you will also change the color of the
speed bars to either cyan or violet. This will allow distant viewers to
recognize that the system is not using the default scale and that the
length of the bars have a different meaning.

If the bar is too long on a scale, you have a very fast computer. To shorten
it and turn the bar violet, press F3 or click the left mouse button while the
cursor is on top of the bar. F3 expands CPU and FPU scales, while F5 expands
the video scale.

If the bar is too short on a scale, you are running on a relatively slow
computer. To lengthen the bar and turn it cyan, press F4 or click the right
mouse button while the cursor is on top of the bar. F4 shrinks CPU and FPU
scales, while F6 shrinks the video scale.

HISTORY AND STANDARDS

From 1984 through early 1993 the original Landmark CPU Speed Test (tm)
gradually gained prominence and became the de facto world standard for
measuring PC computing speed. There are several reasons for its rise to
popularity:

1. Standard - it compared the speed of the computer it ran on to the speed
of the first and only de facto standards that ever existed for personal
computers: the IBM PC and the IBM AT. IBM never changed the architecture
of either computer, but replaced them with the PS/2 line in 1987 and took
the PC and AT out of production. Since IBM will never change the PC or AT,
those will always be stable standards of comparison for PC performance,
and Landmark will be the performance measurement standard. The original PC
used an Intel 8088 CPU and optional 8087 FPU running at 4.77 MHz. The
original AT used an Intel 80286 CPU running at 6 MHz, and a later version
ran at 8 MHz; in both versions the optional 80287 math chip ran at 6 MHz.

2. Visibility - the Landmark speed bar that reached horizontally from left
to right across the screen was visible and relatively readable from a
distance of 15 to 30 meters (50 to 100 feet). This made it ideal for
dealer showrooms and trade shows, so manufacturers and resellers enjoyed
using it to show off their computer's speed.

3. Credibility - it was the most accurate benchmark test on the market
because it considered a variety of factors that other programs did not, and
it showed performance relative to the PC and AT. Other benchmark programs
gave unreliable or misleading information:

Norton System Index (SI) was too simple and overrated AT performance relative
to the PC.

MIPS (millions of instructions per second) used an instruction mix that was
somewhat arbitrary.

Whetstone, a test of general computing combined with floating point or
scientific math calculations, was originally written in FORTRAN, so the
results were badly skewed by both compiler efficiency and the ratio of
floating point math instructions to arithmetic and loop instructions.
Dhrystone, a test of general computing performance, was originally developed
to test ADA compiler efficiency, but was converted to the C language for
execution on the PC. Because of the plethora of C compilers in use, it
suffered from the same kind of skewing as Whetstone.


4. Results - The speed test displayed its results graphically with fixed
scaling, and it beeped while it gave continuous screen updates. All the
other programs, such as SI, MIPS, Power Meter, CheckIt, and QA Plus, ran
through once and stopped. Thus, in real time it showed how much system
performance degraded during network accesses or other multitasking program
activities. Furthermore, the instant update gave immediate feedback to
users, and gratified them that the system was actively running. Finally,
benchmark graphic displays in QA Plus and CheckIt automatically scaled test
results so that their speed bars had no meaning when viewed from a distance.
