The term data compression refers to reducing the number of bits of information that should be saved or transmitted. You can do this with or without losing information, which means that what will be erased at the time of the compression can be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the data and its quality shall be identical, whereas in the second case the quality shall be worse. You can find various compression algorithms that are better for different sort of info. Compressing and uncompressing data in most cases takes a lot of processing time, therefore the server executing the action should have plenty of resources to be able to process your info quick enough. An 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 particular 1s and 0s.

Data Compression in Website Hosting

The compression algorithm which we employ on the cloud internet hosting platform where your new website hosting account will be created is called LZ4 and it's used by the exceptional ZFS file system that powers the system. The algorithm is much better than the ones other file systems work with since its compression ratio is much higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed since this happens quicker than info can be read from a hard drive. For that reason, LZ4 improves the performance of any website hosted on a server that uses the algorithm. We use LZ4 in one more way - its speed and compression ratio make it possible for us to generate a couple of daily backups of the full content of all accounts and keep them for 30 days. Not only do these backups take less space, but their generation does not slow the servers down like it often happens with other file systems.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform which runs using the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm named LZ4, that is a lot better than alternative algorithms regarding compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 much faster 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 websites running on a platform that uses LZ4 compression perform faster since the algorithm is most effective when it processes compressible data i.e. web content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep need less space and they are generated a lot faster, which allows us to keep a couple of daily backups of all your files and databases.
