Data compression is the compacting of data by decreasing the number of bits which are stored or transmitted. Because of this, the compressed info will take substantially less disk space than the original one, so extra content might be stored on identical amount of space. You'll find different compression algorithms that function in different ways and with some of them just the redundant bits are erased, therefore once the data is uncompressed, there's no loss of quality. Others erase unnecessary bits, but uncompressing the data subsequently will lead to reduced quality in comparison with the original. Compressing and uncompressing content needs a large amount of system resources, in particular CPU processing time, therefore each and every web hosting platform which uses compression in real time needs to have enough power to support this feature. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of keeping the entire code.

Data Compression in Shared Web Hosting

The compression algorithm employed by the ZFS file system that runs on our cloud web hosting platform is called LZ4. It can improve the performance of any Internet site hosted in a shared web hosting account on our end because not only does it compress data significantly better than algorithms used by alternative file systems, but also uncompresses data at speeds that are higher than the hard disk drive reading speeds. This is achieved by using a great deal of CPU processing time, which is not a problem for our platform considering the fact that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it allows us to create backups much more rapidly and on less disk space, so we will have several daily backups of your files and databases and their generation will not change the performance of the servers. In this way, we could always restore all content that you could have deleted by mistake.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account shall be created on a cloud platform which runs using the innovative ZFS file system. The latter uses a compression algorithm known as LZ4, which is a lot better than various other algorithms with regard to compression ratio and speed. The gain is noticeable especially when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a HDD. This is the reason why sites running on a platform that employs LZ4 compression perform faster as the algorithm is most efficient when it processes compressible data i.e. website content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep require less space and they're generated a lot quicker, which allows us to have a number of daily backups of your files and databases.
