The term data compression refers to decreasing the number of bits of info which needs to be saved or transmitted. This can be achieved with or without losing data, which means that what will be removed during the compression shall be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the info and the quality shall be identical, while in the second case the quality shall be worse. There are different compression algorithms that are more effective for different sort of information. Compressing and uncompressing data generally takes a lot of processing time, therefore the server carrying out the action must have sufficient resources in order to be able to process the info fast enough. An example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 inside the binary code rather than storing the actual 1s and 0s.

Data Compression in Shared Website Hosting

The cloud internet hosting platform where your shared website hosting account is generated uses the innovative ZFS file system. The LZ4 compression method that the aforementioned uses is greater in lots of aspects, and not only does it compress data better than any compression method which some other file systems use, but it is also a lot faster. The gains will be significant especially on compressible content like website files. While it may sound illogical, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of any site hosted on our servers will be boosted. The better and faster compression rates also allow us to produce a number of daily backups of the whole content in each web hosting account, so should you delete anything by mistake, the last backup which we have won't be more than a couple of hours old. This is possible because the backups take considerably less space and their generation is fast enough, so as to not influence the performance of our servers.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform which is run on the advanced ZFS file system. The aforementioned uses a compression algorithm named LZ4, that is significantly better than alternative algorithms in terms of compression ratio and speed. The gain is apparent particularly 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. That is why websites running on a platform which employs 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 require less space and they are generated a lot faster, which allows us to have a number of daily backups of your files and databases.
