The term data compression identifies decreasing the number of bits of information which has to be stored or transmitted. This can be achieved with or without the loss of information, which means that what will be removed during the compression can be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the information and the quality will be the same, while in the second case the quality will be worse. There're various compression algorithms that are more efficient for various type of information. Compressing and uncompressing data frequently takes a lot of processing time, which means that the server executing the action needs to have enough resources to be able to process the data fast enough. One simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 within the binary code as an alternative to storing the actual 1s and 0s.

Data Compression in Shared Hosting

The compression algorithm which we work with on the cloud web hosting platform where your new shared hosting account will be created is known as LZ4 and it's applied by the revolutionary ZFS file system that powers the system. The algorithm is greater than the ones other file systems work with because its compression ratio is much higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed as this happens even faster than data can be read from a hdd. Therefore, LZ4 improves the performance of any Internet site hosted on a server which uses the algorithm. We use LZ4 in an additional way - its speed and compression ratio make it possible for us to produce a couple of daily backups of the entire content of all accounts and keep them for a month. Not only do the backups take less space, but also their generation does not slow the servers down like it can often happen with many other file systems.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform which runs using the advanced ZFS file system. The latter uses a compression algorithm called LZ4, that is much better than various other algorithms with regard to compression ratio and speed. The gain is apparent especially 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 disk drive. That's why 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. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep require significantly less space and they are generated faster, which allows us to keep several daily backups of your files and databases.
