The term data compression identifies reducing the number of bits of information which should be saved or transmitted. You can do this with or without the loss of info, which means that what will be erased throughout the compression will be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the data and the quality shall be identical, whereas in the second case the quality shall be worse. You will find various compression algorithms that are more efficient for various sort of information. Compressing and uncompressing data normally takes lots of processing time, which means that the server performing the action must have sufficient resources to be able to process your info quick enough. A simple example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 in the binary code rather than storing the particular 1s and 0s.

Data Compression in Hosting

The compression algorithm that we work with on the cloud web hosting platform where your new hosting account shall be created is named LZ4 and it's used by the cutting-edge ZFS file system which powers the system. The algorithm is superior to the ones other file systems use because its compression ratio is a lot higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed since this happens faster than information can be read from a hard drive. For that reason, LZ4 improves the performance of each and every website stored on a server that uses this algorithm. We use LZ4 in an additional way - its speed and compression ratio let us produce several daily backups of the whole content of all accounts and keep them for a month. Not only do the backup copies take less space, but their generation does not slow the servers down like it often happens with alternative file systems.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform that runs on the advanced ZFS file system. The latter uses a compression algorithm called LZ4, that's a lot better than all other algorithms in terms of compression ratio and speed. The gain is significant 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 disk drive. Because of this Internet sites running on a platform which uses LZ4 compression perform better because the algorithm is most effective when it processes compressible data i.e. site content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep require a lot less space and they're generated faster, which allows us to store a couple of daily backups of your files and databases.
