The term data compression refers to lowering the number of bits of information that has to be stored or transmitted. You can do this with or without the loss of information, which means that what will be removed at the time of the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the content and the quality shall be identical, whereas in the second case the quality will be worse. You will find various compression algorithms which are better for different kind of data. Compressing and uncompressing data frequently takes plenty of processing time, which means that the server performing the action needs to have adequate resources in order to be able to process your data quick enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 in the binary code instead of storing the actual 1s and 0s.
Data Compression in Cloud Website Hosting
The cloud hosting platform where your cloud website hosting account is generated uses the innovative ZFS file system. The LZ4 compression method that the aforementioned uses is superior in many aspects, and not only does it compress data better than any compression method that other file systems use, but it's also considerably faster. The gains will be significant in particular on compressible content which includes website files. Despite the fact that it may sound irrational, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk, so the performance of every site hosted on our servers shall be improved. The better and faster compression rates also make it possible for us to generate a number of daily backups of the entire content in each Internet hosting account, so if you delete something by accident, the last backup which we have won't be more than several hours old. This is possible as the backups take a lot less space and their generation is quick enough, to not change the performance of our servers.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account shall be created on a cloud platform which runs on the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that is much better than alternative algorithms when it comes to compression ratio and speed. The gain is significant particularly 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 drive. This is the reason why sites running on a platform which uses LZ4 compression perform faster because the algorithm is most effective when it processes compressible data i.e. site content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need a lot less space and they're generated faster, which enables us to keep several daily backups of all your files and databases.
