Best Free Internet Accelerator


Unlike most other accelerators which provide caching on your own PC, Google Web Accelerator (GWA) uses  caching on Google's own dedicated web servers to accelerate browsing.

It also uses a number of other techniques to speed things up, including compression of html pages and the use of pre-fetching links. GWA automatically installs into Internet Explorer and Firefox browsers, and can be manually configured to work with other browsers.

To protect user privacy, the accelerator does not function while you are connected to secure sites, such as internet banking. Does it work? You bet! Most users, myself included, report improvements of 10-40% in browsing speeds.

There are, however, some caveats:

  • It's only available for Windows XP, Windows 2000 SP3+, and Vista.
  • The product is optimized for broadband use, so modem users may experience little or no gain.
  • The system currently works best within the USA and Europe, and users located in other areas will only see a small benefit.
  • There are some potential privacy issues involved, so all users should closely read what Google has documented on the subject. Personally, I don't have a problem with the privacy issues, but your mileage may vary.

Those reservations aside, this is a terrific product. It provides, at no cost, most of the benefits of expensive commercial web acceleration services like Propel. Download it and see if it speeds up your browsing; if it doesn't, it's perfectly easy to uninstall.

NB: Some Vista users have reported problems with this program (ie. that it simply doesn't work, or that it blocks access). The root causes remain very unclear. It may be a "64-bit problem", or an "SP1 problem", or it may affect only those PCs which are connected to external or internal "private" networks. Because I'm not aware of any uninstallation difficulty, my advice remains the same: you have nothing to loose by trying it.

Works nicely but take a look at your CPU
Mine reacts at a very annoying way. The mouse curser keeps changing to the "loading curser". The program raises my CPU with approx. 4% every 5 sec.

I use Vista home edition, but I think to remember the same problem on my XP computer when installing the program at it a couple of years ago.

Btw. sorry for my bad english.. I'm danish ;P

Thanks for your input.

You'll notice that there is a note in the review about problems with Vista. Don't be concerned about your English. Like most Danes, I'm sure you speak it almost perfectly. You should hear what we Brits do to foreign languages!

Are there any alternatives to Google that work in Australia?

Another way to speed up the internet is to use a service like You point your DNS to them, create a free account, decide what you want to filter out, and voila! You can surf the internet faster, depending on what you have filtered out (like ads, commercial pages, porn, etc). The huge size of their DNS cache is also supposed to make website lookups faster. I think they are situated somewhere in the States, so locals over there should benefit the most.

Another tool I've heard of is FastCache from, although I did not try it out myself yet. The reason being: I see a lot of reports about trojans and stuff that is related to fci.exe ... which happens to be the filename of FastCache. If anyone is brave enough to try it out in a safe environment, please report back here.

Even after installation it(GWA) no longer works.

Google Web Accelerator has now been discontinued and it does not work at all, so unless the editor includes some software that can do the same job there is no reason in keeping this category up

What about this product: SG TCP Optimizer?

More info here:

Users in India can get ONSPEED for free at this site :
ONSPEED is a great program and works on broadband too.
For people on slower networks there are some free alternatives.
1)The Opera Turbo feature in Opera 10 beta is great and development is on.
2)Toonel ( is one option. It requires Java and one inconvenience is that it does not work in the background. However u can use it along with trayit to remove that discomfort.
3)Trafficcompressor ( is a limited version of its shareware counterpart. Haven't tried it much.

Note that the above proxy-based software have another benefit that they will compress traffic(useful for users who are on broadband limits like I have a 1.5 gb monthly limit)

For local tweaks the best software is TCPoptimizer . cFOSSpeed(alas not free) is great too.
DNS Caching helps to improve response slightly. It is enabled by default in Google Chrome or I found a another program mentioned below (fastcache). dns caching may have security concerns. Use a good antivirus along with it

Finally things like adblocking, flashblocking and turning off javascript(as in Noscript addon for firefox) can help u as well.

Hope this helps.

There's always fasterfox and fasterfox lite for firefox.

by sa1 on 8. June 2009 - 8:31  (23302)

It was me who posted the comment below. I too used to use fasterfox without the prefetching but its not developed any more.(Still works on ff3 with tweaks) Now fasterfox lite seems to be in development. Thats good.

I tried this speed guide TCP Optimizer and it worked really well for improving web page downloading speeds. But I soon got system error messages that resulted in my system being shut down, after every use. And I am 1000% postive it is associated with this download. Because when i delected the speedguide optimizer which wasn't easy to do, my system problems cleared up ASAP.

im finding another one

This is an indirect comment.

I am looking for a program that helps me manage and monitor my internet connection better than the tools in Windows.

When I start my PC I want it to automatically connect me and deal with any initial connection problems I might have such as partial connection problems when a disconnection and reconnection is needed.

If my ISP disconnects me I want it to reconnect after a set delay. If the the connection attempt failed I want a reconnect attempt after a set time period.

I want to know all the programs that are uploading or downloading with a history log.

I want statistics to help me assess the quality of my ISP.

I have been searching for such an application for some time but nothing does it all.

Can you give me names of applications that do these things? Thanks in advance.

As this page is not visited that often you would get a more comprehensive response if you post in the forum.

But the service itself doesn't work. You can't connect to Google's servers.

Hi fellow gizmo heads, since this is the only web accelerator recommendation, but the comments cast doubt that it is still functional, can we get other options and/or an update of this page. Thanks. And again for all your good work.
