Depending on how much you spend staying up on web browsers, you’ve probably heard the cry of Opera did it first more than once (though the low-hanging fruit, browser tabs, wasn’t technically Opera first). When Google announced that Chrome would offer a data compression mode, you may have figured you’d hear it again owing to Opera Mini.
Chrome for mobile devices has been climbing in use, partly because Android devices have started to move away from the default Android browser (though this doesn’t affect all the Android 2.x devices and many of the 4.x devices that will be out there for a while). By adding support for data compression, Chrome is that much more appealing to users who have bandwidth caps, poor connections, or any other factor that limits how well they can see fat pages. Interestingly, some of the data compression comes from converting all the images to WebP (ol’ Gil has finally found a way to make that format work). Chrome also automatically puts you into Safe Browsing mode as part of its compression process.
So I fired up both browsers, chose a list of web pages/sites that I haven’t surfed using either of them, dropped into 3G and started my compressed surfing. These are the results:
This test was by no means rigorous or scientific. While Chrome compressed just a bit better overall, I felt like the experience was slower than on Mini. Chrome was also served much more data, perhaps owing to browser detection scripts offering more “features” to Chrome, or Mini’s rendering engine just ignoring some of the elements it didn’t know.
For those who have decided that Google is the great new evil, you may want to consider that Google proxies are between you and the web for every request when using Chrome’s compression. For Mini users the same is true of Opera’s servers, but far fewer people seem to be concerned about demonizing Opera Software. How much stock you put into Google’s Safe Browsing technology behaving as some sort of censor is up to you and your own paranoia. I don’t much care either way, but some folks might. As someone who’s used Opera Mini for years when I travel outside the U.S., I’m very comfortable with it and doubt I’ll switch — it’s easier for me to just fire up Mini than it is to navigate Chrome’s menus to enable compression.
Yep, I expect more use might extract more of a spread in the results. Visiting different sites may also yield different results as well, so I wanted to avoid anything that wasn't a one-to-one comparison.
