How does this page calculate my System/CPU speed?
Actually, this isn't just a web page; it's a web page that uses a Java Script. It's the Java Script that calculates the System/CPU speed and approximates the CPU’s clock speed in MHz.
This benchmark is calculated by using the time it takes to run that script on your particular computer configuration.
The CPU MHz or megahertz are calculated to be consistent with Intel Pentium Class processors.
The difference between this version and previous versions of this benchmark is that Version 5 includes the movement of data through
the processor to help determine the true speed on high-end systems. Under previous versions only the time that it took to run the
application was important. Movement of data wasn't important in the timing equations as all the machines tested moved the same
amount of data but in different times. High-end machines are seeing larger amounts of data moved in very short but still variant
quanta of time.
For those of you that are interested the CPU ~MHz should come out correctly on all Intel based computer systems.
All other processors such as AMD, for example, will give a value that would compare to what an Intel would be
clocked at to obtain the same results.
Getting rediculous numbers? This PC isn't that fast?
Recent changes in browser technology and the many browsers available today have been known to cause benchmarks
that are excessively high. This is the result of browser designers writing more efficient processing code.
We suggest using a different browser. The Windows standard system browser Internet Explorer usually corrects
the problem and gives dependable results.
If you’re running on a 64 bit system and are also running a 64 bit browser you may see a doubling of the CPU-speed
when compared to running a 32 bit browser on the same system. All browser are not the same internally.
These differences account for results that seem strange.
If the problem persists in every browser you try, drop the Webmaster a note.

I have Multiple CPU Processors are they all being tested?
In a Multiple CPU systems the CPU/Speed test can only test those processors assigned by the operating system being used.
From our experience we’ve seen for example that a Windows 2000 system will assign two CPUs to the CPU/Speed.
While a Windows XP system will only allocate one CPU to the CPU/Speed test and thus Windows XP generally gives a lower response numbers.
The overall response numbers obtained by this test apply to the speed of the processor based on a single CPU processor system.
Expect Dual processor system working together on a balanced OS to provide significantly higher results than either single processor alone.
Why do I get different speed results each time I run
The System/CPU Speed Test?
In a multi-tasking system all tasks are not treated or programmed equal.
Other programs or applications running in the background on your computer can delay the Java Script that calculates the benchmark.
Each running program has their own capacity for CPU usage and may change the speed limit. The best results are obtained when this program runs with the minimum of other applications.
If your system doesn't do what you think it should then there is probably something wrong that is slowing it down.
This page has helped successfully in spotting problems on systems when the results are wildly different.
This usually meaning that some other unknown task is taking up most or all of your computers processing power.
System problems that were causing substantial system slowdowns were spotted as poor results or wildly different
results each time the page was accessed. A virus or other malicious process could cause this.
I thought my System/CPU was supposed to be faster.
Why does the Speed Test come up with a lower figure?
Many things will change the way the speed test works on different PC types.
The main ones are the operating system, browser type and the number of additional running tasks.
The fewer tasks that are running the better your results will be.
Next, this page can only measure the time it takes your chosen browser to execute the script.
The benchmark is only that, “a mark” to give you some idea of how you’re particular system configuration stacks up against the competition. Every effort has been made to lessen the effects of various browsers and operating systems. We also ran tests on MacIntosh and Sun Sparc workstations with reasonably accurate results.
This test can not give exact results as to the actual CPU MHz clock speed. This test can only give you some idea of how well your choice of operating system and browser are working together.
If there are many other applications running on your machine then this may result in a depressed value for the System/CPU figures. In conclusion, some systems are just faster than others.
I'm getting a big slowdown. Could my Internet Service Provider (ISP) be the cause of my problem?
Perhaps.
The delay could be at your ISP, or it could be
elsewhere. (See the explanation
above, but if you're consistently getting
System/CPU Speed Test
results that are substantially below expectations, the root problem is most likely your
browsers or hidden applications running on your system. You might want to check for Spy ware or run a Virus scan to be certain
that you don't have a system problem.
I'm using a modem. Does this make any difference?
No! There could be a slowdown in loading the initial page, but once it's loaded the modem speed will make no difference.
You can use the re-test button to test again if you think you had an initial problem. The page should load from your cache and not our server.
Can I use the Speed test to Spot problems with my PC?
Yes, you can use the PCExpress Speed test to help you spot potential problems with your PC. Let’s say, for example,
you’re running a 2500MHz (2.5GHz) processor and the Speed test says your PC is running at 1200MHz. Unless you’re
running a laptop on battery power, this result would indicate that your PC has a serious problem. A slight variation
in speed can be expected but extremes indicate a major malfunction. This result could indicate a virus, spyware or
other malicious software is running on your PC and taking up much of your processors compute power.
I'm using a Laptop. How come the test gives a much lower result when I'm not plugged into the wall outlet?
Your laptop may employ SpeedStep.
Many laptops now use SpeedStep technology, which brings desktop CPU speeds to laptop users.
SpeedStep technology helps your laptop batteries last longer because the chip set will slow down your processor speed when you're running on battery power. This technology helps conserve the battery life and allows you to use your laptop longer while not plugged in to a wall out let for charging.
When you plug back into an AC line, you receive the maximum CPU performance that your laptop can provide. Intel created SpeedStep chips in response to market research showing that users run laptops from AC lines about 70 percent of the time. Many other manufactures have since adopted this technology.
