Data compression is the lowering of the number of bits that have to be saved or transmitted and the process is quite important in the web hosting field due to the fact that info located on HDDs is generally compressed so as to take less space. You'll find various algorithms for compressing data and they provide different efficiency based upon the content. Many of them remove only the redundant bits, so that no data will be lost, while others erase unnecessary bits, which leads to worse quality when the particular data is uncompressed. This method uses a lot of processing time, therefore a web hosting server needs to be powerful enough in order to be able to compress and uncompress data instantly. An instance how binary code could be compressed is by "remembering" that there are five sequential 1s, for example, rather than storing all five 1s.
Data Compression in Website Hosting
The cloud internet hosting platform where your website hosting account will be generated works by using the innovative ZFS file system. The LZ4 compression method that the latter employs is superior in various aspects, and not only does it compress info better than any compression method which a variety of other file systems use, but it is also a lot quicker. The benefits can be significant especially on compressible content like website files. Although it could sound irrational, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of each and every site hosted on our servers shall be improved. The better and quicker compression rates also allow us to make a large number of daily backups of the full content in each and every web hosting account, so if you delete something by accident, the last back-up copy which we have will not be more than a few hours old. This is possible as the backups take a lot less space and their generation is fast enough, so as to not influence the performance of the servers.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account shall be created on a cloud platform that runs on the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm called LZ4, that's far better than all the other algorithms with regard to compression ratio and speed. The gain is significant particularly when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk. Because of this websites running on a platform that employs LZ4 compression perform faster as the algorithm is most efficient when it processes compressible data i.e. web content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep take less space and they're generated quicker, which enables us to keep multiple daily backups of all your files and databases.
