Data compression is the compacting of info by lowering the number of bits which are stored or transmitted. Thus, the compressed information will need considerably less disk space than the original one, so more content might be stored using the same amount of space. You will find various compression algorithms which work in different ways and with some of them just the redundant bits are deleted, so once the data is uncompressed, there is no loss of quality. Others remove unnecessary bits, but uncompressing the data later will result in reduced quality in comparison with the original. Compressing and uncompressing content takes a significant amount of system resources, in particular CPU processing time, so any hosting platform that uses compression in real time should have ample power to support this attribute. An example how data 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 actual code.

Data Compression in Shared Hosting

The cloud hosting platform where your shared hosting account shall be generated works by using the cutting-edge ZFS file system. The LZ4 compression method which the latter employs is better in a number of aspects, and not only does it compress data better than any compression method that a number of other file systems use, but it's also considerably quicker. The gains will be significant in particular on compressible content like website files. Even though it may sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk drive, so the performance of any site hosted on our servers shall be enhanced. The better and faster compression rates also allow us to make a large number of daily backups of the full content in every single hosting account, so should you delete anything by mistake, the last backup that we have won't be more than several hours old. This can be done as the backups take considerably less space and their generation is fast enough, to not change 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 latter uses a compression algorithm named LZ4, which is a lot better than all other algorithms with regard to compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard drive. Because of this websites running on a platform which uses LZ4 compression perform faster because the algorithm is most effective when it processes compressible data i.e. site content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep require much less space and they are generated a lot quicker, which allows us to have several daily backups of your files and databases.
