Note: This FAQ is also useful if you are
simply interested in figuring out exactly how much acceleration
you are getting. With Propel Accelerator in place you should
be seeing a very noticeable increase in surfing speed -- an
average of 3X acceleration, with some pages appearing up to
5 times faster. To get a better idea of the types of speed
improvements you should expect to receive, see the Propel
Accelerator Technical Overview. It contains a table showing
typical speed improvements accessing several popular Web sites
such as Amazon, c/net, and Priceline, among others, over dial-up
modems. In our studies Web page performance can be significantly
influenced by a number of factors including:
- Amount of data required to display a Web page. If you haven't
already done so, try a higher Graphics Acceleration setting
such as Level 4 or 5. For complete details on graphics acceleration
options Click Here.
- Connection speed, which can vary significantly even when you
are using the same ISP and dialing in to the same phone number.
- Available memory (RAM), which can vary depending on the number
of applications you are running. Even though Propel Accelerator
can run with very little available RAM, acceleration benefits
can be further optimized if you have plenty of free RAM available.
If you are not seeing a very noticeable increase in surfing
speed with Propel Accelerator (or perhaps no improvement at
all), please take the following steps:
1. First you need to
make sure that Propel Accelerator is working properly. When
you browse a typical Web site you should see arrows moving over
the Propel Accelerator icon (blue propeller in the Windows taskbar,
near the clock). If you are not seeing the arrows or are getting
little to no acceleration Click Here for important Troubleshooting
Tips. It only takes a few minutes to make sure that Propel Accelerator
is working for you.
2. If Propel is working properly, the next
step is to measure the performance increase you are getting:
- The mouse-over. The quickest/fastest way to determine the amount
of acceleration you are getting is to move your mouse over the
Propel Accelerator icon. A small pop-up will appear telling
you that Propel Accelerator is enabled and reporting the average
speed up you are getting.
- Performance meter. Click on the Propel menu and choose Performance
Meter and Test Page... In addition to displaying your average
speed-up, you'll also see your effective speed in kbps (kilobits/second)
based on Propel's compression of text and graphics.
- Performance Test Page. You'll also find a button
that will take you to the Propel Accelerator Performance Test Page
(PTP).
- Enable/Disable Propel Accelerator. You can use the Disable Propel
Accelerator menu command to turn off Propel Accelerator for
an hour or two of surfing, then turn it back on and use it for
a similar amount of time.
- Independent verification. Numion provides a "stopwatch" for
timing page loads as well as many other interesting timing tools:
To use the Numion stopwatch to test Propel Accelerator:
- Choose Disable Propel Accelerator from the Propel Accelerator
menu
- Go to the Numion StopWatch page
- Enter the URL of your choice to be measured
- Click Start StopWatch
- Write down the results
- Enable Propel Accelerator
- Time the same URL
- Compare the results.
Try the test several times. You can also experiment with clearing
your browser cache and the Propel Accelerator cache.
- Numion has another interesting test involving popular Web sites:
- First, disable Propel Accelerator
- Go to the Numion home page
- Click on the Your speed button
- Choose a location (or the world)
- Click Start!
- Write down your results
- Enable Propel Accelerator
- Run through steps 2-6
- Compare the results
