Data compression is the compacting of data by lowering the number of bits that are stored or transmitted. As a result, the compressed information will take substantially less disk space than the original one, so extra content can be stored on the same amount of space. You will find many different compression algorithms that work in different ways and with several of them only the redundant bits are erased, so once the info is uncompressed, there is no loss of quality. Others delete unnecessary bits, but uncompressing the data at a later time will lead to lower quality in comparison with the original. Compressing and uncompressing content consumes a huge amount of system resources, and in particular CPU processing time, therefore every hosting platform that uses compression in real time should have adequate power to support that attribute. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" what number of consecutive 1s or 0s there should be instead of keeping the entire code.

Data Compression in Shared Hosting

The ZFS file system that runs on our cloud web hosting platform employs a compression algorithm identified as LZ4. The latter is substantially faster and better than any other algorithm on the market, 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 drive, which improves the performance of Internet sites hosted on ZFS-based platforms. As the algorithm compresses data very well and it does that very fast, we are able to generate several backups of all the content kept in the shared hosting accounts on our servers on a daily basis. Both your content and its backups will need less 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 kept.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform that is run on the innovative ZFS file system. The aforementioned uses a compression algorithm called LZ4, that's a lot better than other algorithms in terms of compression ratio and speed. The gain is apparent particularly when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. Because of this sites running on a platform which employs LZ4 compression perform faster because the algorithm is most effective when it processes compressible data i.e. web content. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep require less space and are generated faster, which enables us to keep a number of daily backups of your files and databases.
