Opera Software today released a new developer version of the Opera browser. Opera 43 build 2431 is the first build of the browser which comes with the recently announced address bar speculative prerenderer feature.
Opera 43 will learn your preferences from your browsing history and habits. For example, if you start typing "nyt.com" in the browser every time, it will eventually learn that and load New York Times in the background. So, New York Times will be opened for you faster.
Another example - it will load search results in the background, so once you click a link from Google Search, it will open instantly.
This will improve the loading speed of your websites.
Here are some more details about this new feature.
How it works
There are two ways the browser can predict what page the user will soon load.
- The current page can point the browser to pre-load a URL via a special < link rel=prerender … > tag.
- It can be determined from the user's actions that he or she is about to load something.
When someone writes in the address bar they are humanly slow. Sometimes it is obvious what they will write after just 1-2 characters but they will just keep writing or arrowing through suggestions for millions or billions of wasted clock cycles.
The prediction is expected to provide in an average of 1 second faster loads from the address bar. This means that a lot of pages and web sites should be opened instantly.
