The term data compression refers to lowering the number of bits of information which needs to be stored or transmitted. You can do this with or without the loss of data, which means that what will be deleted throughout the compression can be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the info and the quality will be the same, whereas in the second case the quality shall be worse. You'll find various compression algorithms which are better for various type of info. Compressing and uncompressing data usually takes a lot of processing time, which means that the server carrying out the action needs to have sufficient 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 just how many should have 0 inside the binary code instead of storing the particular 1s and 0s.

Data Compression in Shared Website Hosting

The cloud hosting platform where your shared website hosting account is made works by using the impressive ZFS file system. The LZ4 compression method which the aforementioned uses is better in various aspects, and not only does it compress info better than any compression method which similar file systems use, but it is also considerably quicker. The gains are 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 each and every site hosted on our servers shall be upgraded. The better and faster compression rates also make it possible for us to produce numerous daily backups of the entire content in each hosting account, so in the event you delete anything by mistake, the last back-up copy which we have won't be more than a few hours old. This can be done because the backups take much less space and their generation is quick enough, to not affect the performance of our servers.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform which is run on the innovative ZFS file system. The aforementioned uses a compression algorithm named LZ4, that's far better than alternative algorithms when it comes to compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk drive. This is the reason why websites running on a platform which uses LZ4 compression perform faster because the algorithm is most effective when it processes compressible data i.e. web content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep require much less space and they're generated faster, which allows us to have a couple of daily backups of all your files and databases.
