Internet faster and more efficiently thanks to Google Brotli

Google announced a new compression algorithm for web pages, called Brotli. Replaces Zöpfli and runs with an efficiency of 20/26% higher than the latter.

With the web sites and services that are becoming increasingly complex, the need to improve the compression algorithms of the pages is becoming more and more, especially in the mobile environment. And it is with this premise that Google wants to offer the best solution, which is called Brotli. Brotli is an algorithm open-source able to offer an efficiency of 20-26% higher than what was possible with Zöpfli, the previous model of the company.

Just like its predecessor, Brotli was designed with the sole purpose of making the loading of web pages more efficiently. It is, according to Google, a ” lossless format that compresses data using a combination of the algorithm LZ77 and Huffman code, with an efficiency comparable to that of the best general compression systems currently available. ” According to data released by Google Brotli should be faster implementation of Deflate more effective.

In tests conducted on Linux 3.13.0 on an Intel Xeon Eg-1650 v2 operating at a frequency of 3.5 GHz, the researchers say that Google Brotli runs with a compression ratio of 3,381: 1 at a rate of compression of 98.3MB/s, if decompression of 334 MB/s. On the same machine, the implementation of Deflate faster is able to compress to 93.5MB/s, if decompress to 323 MB/s, but with a compression ratio less precise equal to 2,913:1.

Google developed the new Brotli hoping to be introduced within several browsers for browsing online, but it is clear that technology is primarily aimed at mobile environment. A compression algorithm most effective results in faster uploads the one hand, but on the other could allow major improvements in the battery life of the devices and a traffic Internet less than equal content.
