On iOS, Apple added the function 9 blocking web content. It will allow users to install extensions that will block ads and other unwanted content in Safari on all levels of the system. According to Owen Williams TNWIt will forever change the web-surfing on your Apple mobile devices.
How it works
The locking mechanism operates such that the incoming content is blocked even before download it. Using the list of websites and scripts blocker processes them at the system level, rather than merely instructs the browser to block them on the page. This significantly increases download speed.
By the way, if you think that most of the time, and Safari spends on traffic load promotional banners, you are wrong. Besides them there are the so-called third-party trackers that collect various data about visitors to sites for their subsequent use for promotional purposes. They also increase the web page loading time.
Apple has implemented a content lock using a new type of applications - specially designed for the extensions that are included in Safari preferences. One of these extensions is
Crystal Dean Murphy from an independent developer. He promises to increase the speed of loading pages in Safari, which is especially noticeable when you connect over the cellular network. The developer has made an impressive graph showing the increase in the speed of loading pages on different sites using Crystal.The cursory real test results are not as eye-popping, but they are there, and they can be seen, as they say, to the naked eye.
Testing
To understand how effective the new general mechanism for content blocking, Owen used Crystal - which, incidentally, is still It is at the stage of closed beta testing - to compare the speed of loading the popular western websites with and without blocker him.
All tests were run in Safari when you connect with 4G LTE (icon Wi-Fi, as well as to display the time and battery adds QuickTime when recording). First page is loaded with disabled Crystal (left), and then - with the included. After each download cache and cookies are cleared, and Safari is restarted to produce the most objective results.
On some sites, the difference is much larger, some - less. For example, to Bloomberg and iMore download speed with or without blocker significantly differs. Both sites with the included Crystal time to boot up completely before advertising generally appears on the screen.
The Next Web and The Verge, on the contrary, show a slight, but still noticeable increase in the speed of loading pages eye.
On other sites like the BBC, the blocker did not help to render pages faster, but prevents long load already after the content of the page appears on the screen. It also affects the performance of Safari.
Some publishers, mostly wealthy, it is possible to achieve better results, and their sites load quickly even with all trackers and advertising. Wall Street Journal and New York Times -Good examples.
Content Safari blockers affect the work at all levels of the system, including a new component Safari View ControllerAnd that means that advertising and inappropriate content will be blocked, and also third-party applications: links to Twitter or Facebook will be able to open faster.
Extensions to block ads on desktop browsers are very popular, and the number of users that use them, is growing every year. On iOS, all is still in its infancy, but with the release of iOS 9, and the advent of extensions-blockers are waiting for us broad prospects. And it's not only fast-loading pages through the cellular network and the lack of annoying advertising, but also more energy efficient and less bandwidth consumption.
benefits of Apple
It is unknown in what way will be subject to lock the expansion content. In fact, they can update lists of objectionable content sources autonomously, so it will be interesting to see whether Apple will add them in the App Store. Most likely, this will happen, because the company also has an interest to benefit from the publishers.
Blocking the Web will force the owners of the media to publish their content in application NewsWhich will be part of iOS 9. There used iAd advertising platform, so it can not be blocked, and Apple in any case receive their profits in the form of deductions.
