Learn precisely what Data Compression is and discover how it may affect your sites as well as the experience of your website visitors.
Data compression is the lowering of the number of bits which should be stored or transmitted and the process is quite important in the internet hosting field as data stored on hard disks is usually compressed so as to take less space. You'll find various algorithms for compressing data and they offer different efficiency depending on the content. A number of them remove only the redundant bits, so no data can be lost, while others remove unneeded bits, which leads to worse quality once your data is uncompressed. This process uses a lot of processing time, so a hosting server needs to be powerful enough to be able to compress and uncompress data in real time. An example how binary code may be compressed is by "remembering" that there're five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Shared Website Hosting
The cloud web hosting platform where your shared website hosting
account shall be made employs the impressive ZFS file system. The LZ4 compression method which the latter employs is better in lots of aspects, and not only does it compress data better than any compression method which a number of other file systems use, but it is also a lot quicker. The gains are significant in particular on compressible content like website files. Despite the fact that it could sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard drive, so the performance of any site hosted on our servers will be upgraded. The better and quicker compression rates also allow us to make multiple daily backups of the full content in each web hosting account, so in the event you delete something by accident, the last backup that we have will not be more than several hours old. This is possible because the backups take significantly less space and their generation is fast enough, so as to not influence the performance of our servers.
Data Compression in Semi-dedicated Servers
The ZFS file system that runs on the cloud platform where your semi-dedicated server
account will be created uses a powerful compression algorithm called LZ4. It's among the best algorithms out there and positively the best one when it comes to compressing and uncompressing web content, as its ratio is very high and it can uncompress data at a faster rate than the same data can be read from a hard drive if it were uncompressed. Thus, using LZ4 will accelerate any site that runs on a platform where the algorithm is present. The high performance requires lots of CPU processing time, which is provided by the multitude of clusters working together as part of our platform. In addition to that, LZ4 allows us to generate several backup copies of your content every day and have them for one month as they'll take much less space than regular backups and will be generated considerably quicker without loading the servers.
