Turbo Mode is one Opera 10's most popular features. In just a month, 3 million people used the new feature, which is also utilized to speed up Opera's mobile browsers for smart phones.  (Source: Opera)
New feature is popular among users in a variety of scenarios

While Firefox and Internet Explorer earn most of the news and publicity, smaller browsers like Google Chrome and Opera are quietly earning more marketshare.  Norwegian-based Opera recently debuted a new browser, Opera 10, which brought improved speed compatibility, and some innovative built-in features.

Among the most popular of the new browser's features is Opera Turbo.  The feature uses server-side compression to deliver webpages faster on slow connections.  It can compress webpages 3 to 4 times, reducing transfer size by up to 80 percent in some cases.  Turbo is located in the lower left-hand corner of Opera 10 and is turned on with a click.

In the first month after Opera 10's release, Opera reports that almost 3 million users worldwide tried the new feature.  They used it to view 668 million compressed Web pages, numbers that indicate that the feature is gaining significant traction.

Users cited a variety of reasons for using the feature.  Some users, forced to use slower connections like dialup or slower DSL conections, used the Turbo mode to help make navigating these slow lines less of a headache.  Other customers who used mobile internet cards or other metered/pay-as-you-go plans turned on Turbo to reduce their data transfer and lower their monthly bills or prevent overages.

Looking forward, Opera is providing support for AT&T's fall smart phone browser lineup (other than the iPhone).  The new "" features Opera Mini, Opera's popular smart phone browser.  DailyTech recently took Opera Mini 5 for a test drive on the Blackberry Storm, and found the latest version to be vastly improved, and much faster than the native browser.  Opera's mobile browsers use many of the same compression techniques that power its PC Turbo Mode.

Not needed for some sites

I'm a web developer and there are steps that websites can take to compress and optimise the content themselves, such as enabling compression on the server for text based files such the HTML and CSS and external JavaScript files (something called GZIP compression). Also images can be compressed/optimised by the web developers as well. Thers's also 'spriting' the images (combining multiple images into one and using CSS to show the bit you want, fewer HTTP requests = faster), and setting far-future expire headers that force the browser to not bother checking for new versions of static files (images, scripts, CSS etc.) = fewer HTTP requests to the server.

Indeed many websites already do this, so I wonder if Opera's Turbo mode would make any difference in these cases?

not exactly a bad suggestion, but there's no need to be a prick about it

The kind of compression used by the Opera's Turbo Mode is a bit different than what the webdevs/servers has used, at least in its paradigm. Most webdevs tries to "optimize" their content, which is a balance between quality & filesize, while Turbo Mode most of the time will choose speed over quality. That works very good in a mobile browser environment where you don't need the images to be in 100% quality because it will only hurt speed without giving any improvements in visual quality. Most users will notice very little differences between 75% compressed JPEGs and 20% compressed JPEGs in a QCIF or CIF resolution.

In a desktop environment, I'd say it's not very good but still it can be handy when you use some GPRS/EDGE connection. It maybe sacrifices quality too much but what's the point of getting good quality contents if the page isn't loading? :p

Oh, and Opera FTW! :-)

Opera's turbo does make a difference in those cases. It wouldn't even be notable if it didn't because just about every site out there uses those techniques.
