Opera has today released version 10 of its browser with a number of features and enhancements that the company hopes will stop it from becoming the forgotten man of browsers. One of its built in features is Opera Turbo, which we'll try and demystify here.
What is Opera Turbo?
Turbo is a technology that Opera claims will make web browsing quicker and easier for users on slow connections. Opera claims that with the technology enabled web pages are compressed by up to 80 per cent, making them load faster on your browser.
If this sounds familiar, it's because Opera is building on its experience with Opera Mini, which did something similar to mobile handsets. Opera has now extended the same principal to the desktop.
How do I get it?
As an end user, you need a compatible browser, which not surprisingly means you'll need to download Opera 10 on the desktop and also Opera Mobile on handheld devices.
What are the advantages?
If you're sitting on a very fast pipe Opera Turbo is not needed, unless you've already burnt through your data cap and are paying extra every time you surf, and want to limit the damage. In fact, on a fast connection it will likely slow things down.
It really comes into its own when you're sitting on a poor connection, perhaps somewhere out in the sticks, perhaps in a coffee shop or on a dodgy Wi-Fi connection.
If you're browsing somewhere remote using a 3G dongle, but a 3G signal is nowhere to be seen, it could really help get you to the information you need.
It's also of benefit to the network operators, as if everyone was using Opera Turbo, they'd be less strain on their networks.
How does it work?
When you make a request for a web page, the request is redirected to Opera's servers, which fetches the page, compresses it down on the fly, and then sends it onto your computer. The layout of pages should not be affected, but images will look heavily compressed. Element such as Ajax should still work, but some parts of the page might require you to click on the page to access them.
In Opera desktop, you can easily turn Opera Turbo on an off with a control that sits at the bottom left of the browser. When it's on, a small indicator shows you how much faster the page is loading than it would with it off, and hovering over it shows you how much data you've saved in KBs.
Alternatively there's an automatic mode, which will engage Opera Turbo whenever it detects a low bandwidth connection.
What about security?
Opera has said that encrypted sites will not go through the compression servers, so that you can communicate directly with SSL servers. The company also says that it does not store any private data.
