Data compression is the lowering of the number of bits which have to be saved or transmitted and this particular process is really important in the web hosting field since info kept on HDDs is usually compressed to take less space. There're various algorithms for compressing info and they have different effectiveness based on the content. Many of them remove only the redundant bits, so that no data will be lost, while others delete unnecessary bits, which leads to worse quality when the data is uncompressed. This process employs a lot of processing time, so a web hosting server has to be powerful enough to be able to compress and uncompress data quickly. One example how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Shared Hosting
The ZFS file system which operates on our cloud web hosting platform uses a compression algorithm named LZ4. The aforementioned is considerably faster and better than every other algorithm you'll find, particularly 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 overall performance of Internet sites hosted on ZFS-based platforms. Since the algorithm compresses data very well and it does that very fast, we are able to generate several backup copies of all the content stored in the shared 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 extremely fast, the backup generation will not change the performance of the web hosting servers where your content will be kept.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting
account shall be created on a cloud platform that runs on the innovative ZFS file system. The latter uses a compression algorithm called LZ4, that is far better than other algorithms regarding compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 a lot faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk. This is why websites running on a platform which employs LZ4 compression perform faster because the algorithm is most effective when it processes compressible data i.e. site content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need much less space and they are generated a lot quicker, which enables us to store multiple daily backups of your files and databases.
