Data compression is the compacting of info by lowering the number of bits that are stored or transmitted. This way, the compressed data takes considerably less disk space than the original one, so more content might be stored on the same amount of space. There are different compression algorithms which work in different ways and with a number of them only the redundant bits are removed, which means that once the information is uncompressed, there's no loss of quality. Others delete excessive bits, but uncompressing the data following that will result in reduced quality compared to the original. Compressing and uncompressing content takes a large amount of system resources, in particular CPU processing time, so every Internet hosting platform which uses compression in real time must have sufficient power to support this feature. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of saving the whole code.
Data Compression in Hosting
The ZFS file system which is run on our cloud web hosting platform employs a compression algorithm called LZ4. The aforementioned is a lot faster and better than any other algorithm out there, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the performance of sites hosted on ZFS-based platforms. Because the algorithm compresses data very well and it does that very fast, we're able to generate several backups of all the content kept in the 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 affect the performance of the hosting servers where your content will be kept.
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 best one when it comes to compressing and uncompressing web content, as its ratio is very high and it can uncompress data much faster than the same data can be read from a hard disk drive if it were uncompressed. That way, using LZ4 will speed up any website that runs on a platform where this algorithm is present. This high performance requires a lot of CPU processing time, which is provided by the numerous clusters working together as a part of our platform. In addition, LZ4 makes it possible for us to generate several backups of your content every day and have them for one month as they'll take a reduced amount of space than regular backups and will be generated much more quickly without loading the servers.
