Internet Surfing Made
Faster with Web Accelerators?
A web accelerator is technically any service that
will speed up the performance of your dial-up Internet access. Web
accelerators are becoming more and more popular as a way to surf
the internet at faster speeds without subscribing to a more expensive DSL or broadband service.
How Does an Accelerator Work?
- Maximizing Your Cache Settings - copies
of sites you visit are saved on your computer.
- Re-routing Your Browser to a "Mirror
Site" - a copy of a site saved on a closer server.
- Pop-up Filtering - blocking Pop-up windows
and automatic webpage redirects.
- Compressing Images - removing finer details
of images to make them load faster.
Should I Use an Accelerator?
Many ISP providers including AOL, MSN, AT&T, Qwest and Earthlink,
now offer Accelerator Services to their dial-up clients and proclaim
that dial-up internet surfing speed can be improved by up to 5 times
faster than "normal." There are even private companies
that allow you to download accelerators independent of your ISP.
For those without access to cable or DSL, this can really feel like
you are zooming through the internet! But before you run out and
install your own accelerator, consider the following:
- Maximizing Your Cache Settings on Your Computer - Keeping
copies of sites you visit in a folder on your hard-drive, means
more memory is used up, spyware and adware programs can be installed
on your hard-drive, and accessing "saved" versions of
webpages may very well keep you from seeing that site's most current
information.
- Re-routing Your Browser to a "Mirror Site"
- a copy of a site on a closer server. For example, say you live
in Louisiana and you want to access Google.com. Well, Google is
located in California, so your Accelerator provider makes a copy
of Google and loads it on a server in Texas. When you type in
Google.com, your accelerator re-routes you to their copy site
in Texas. Theoretically, you connect to the site faster, but you
are gaining a couple seconds or even nano-seconds of speed to
connect to a copy.
- Pop-up Filtering - blocking Pop-up windows and automatic
redirects. Ah, the annoying pop-ups... Use your browser's preinstalled
pop-up blocker and set it to ask you if you want the page blocked.
Sometimes there is information you might actually want from a
pop-up... and you certainly don't want to stay on a webpage that
has nothing on it if it has been moved and there is an automatic
re-direct to the new page!
- Compressing Images - removing finer details of images
to make them load faster. This would include most banner ads and
Flash illustrations as well as graphics and photographs. Many
accelerators now offer the option to not compress images, or to
compress them less. However, this potentially defeats the purpose
of an accelerator as images are typically the parts of a website
that slow the page loading process to begin with! Besides, what
good is that new monitor you bought with the ability to view millions
of colors when you go and compress the colors to merely 256 or
even 128?
Most website designers do not care much for "accelerators"
as we feel they give the user merely an illusion of speed and that
the price for this illusion is too high. You may find the faster
load times a joy and do not mind the loss of image quality and other
compromises. If you are still not sure, call your Internet Service
Provider (ISP) and ask their advice.

| This 5K image should take about 3 seconds to load on a 28k
modem. |
Mild Compression and the image will load in 2 seconds.
Note the "banding" |
High Compression and the image loads in 1 second. Note
the loss of color. |
Do I have
an Accelerator on my Computer?
Check the images of Saturn above. Do they all look pretty much
the same? Then you may very well, have an accelerator. Still not
sure? View the full-sized image at NSSCD
Photo Gallery - if the image loads quickly but is banded or
fuzzy, then you probably do. Call your Internet Service Provider
(ISP) and ask them for advice on how to manage your accelerator,
or how to remove it if you prefer. (P.S. If the NSSCD link doesn't work,
then try this one: Saturn
