The term data compression refers to reducing the number of bits of information which has to be stored or transmitted. This can be done with or without the loss of info, which means that what will be deleted in the course of 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 the same, while in the second case the quality will be worse. There're different compression algorithms which are better for various type of data. Compressing and uncompressing data often takes plenty of processing time, which means that the server performing the action should have sufficient resources in order to be able to process the info fast enough. An example how information can be compressed is to store just how many consecutive positions should have 1 and just how many should have 0 within the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Shared Web Hosting
The compression algorithm that we employ on the cloud internet hosting platform where your new shared web hosting account will be created is named LZ4 and it is used by the revolutionary ZFS file system which powers the system. The algorithm is a lot better than the ones other file systems employ since its compression ratio is higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than data can be read from a hdd. As a result, LZ4 improves the performance of any website located on a server which uses this algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to generate several daily backups of the entire content of all accounts and keep them for a month. Not only do our backups take less space, but their generation won't slow the servers down like it often happens with alternative file systems.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account shall be created on a cloud platform which runs using the innovative ZFS file system. The latter uses a compression algorithm called LZ4, that's a lot better than alternative algorithms regarding compression ratio and speed. The gain is noticeable particularly when data is being uncompressed and not only is LZ4 a lot faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. That is why websites running on a platform that employs LZ4 compression perform better as the algorithm is most efficient when it processes compressible data i.e. website content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep take a lot less space and are generated a lot faster, which allows us to have a number of daily backups of all your files and databases.
