Data compression is the compacting of information by decreasing the number of bits that are stored or transmitted. As a result, the compressed information will take considerably less disk space than the original one, so extra content might be stored using the same amount of space. There are many different compression algorithms which work in different ways and with a number of them just the redundant bits are erased, so once the info is uncompressed, there's no decrease in quality. Others erase unnecessary bits, but uncompressing the data later will result in reduced quality in comparison with the original. Compressing and uncompressing content requires a large amount of system resources, in particular CPU processing time, therefore any hosting platform that employs compression in real time must have sufficient power to support this attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of saving the whole code.

Data Compression in Web Hosting

The ZFS file system which runs on our cloud web hosting platform uses a compression algorithm identified as LZ4. The aforementioned is considerably faster and better than every other algorithm you can find, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the performance of Internet sites hosted on ZFS-based platforms. Because the algorithm compresses data quite well and it does that quickly, we're able to generate several backups of all the content kept in the web hosting accounts on our servers on a daily basis. Both your content and its backups will need reduced space and since both ZFS and LZ4 work very quickly, the backup generation will not influence the performance of the web hosting servers where your content will be stored.

Data Compression in Semi-dedicated Hosting

The ZFS file system which runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It's one of the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data at a faster rate than the same data can be read from a hard drive if it were uncompressed. This way, using LZ4 will boost every site that runs on a platform where the algorithm is present. The high performance requires lots of CPU processing time, that is provided by the numerous clusters working together as a part of our platform. In addition, LZ4 enables us to generate several backups of your content every day and save them for a month as they will take a smaller amount of space than typical backups and will be generated considerably quicker without loading the servers.
