The term data compression describes lowering the number of bits of data which should be saved or transmitted. This can be done with or without losing info, so what will be removed throughout the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the info and its quality shall be the same, whereas in the second case the quality shall be worse. You can find various compression algorithms that are more effective for various sort of info. Compressing and uncompressing data frequently takes plenty of processing time, therefore the server executing the action needs to have adequate resources in order to be able to process your info 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 as an alternative to storing the particular 1s and 0s.
Data Compression in Shared Web Hosting
The cloud web hosting platform where your shared web hosting account shall be generated uses the cutting-edge ZFS file system. The LZ4 compression method which the latter employs is better in a number of aspects, and not only does it compress information better than any compression method which many other file systems use, but it is also a lot faster. The gains can be significant in particular on compressible content like website files. Even though it could sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk drive, so the performance of any Internet site hosted on our servers will be upgraded. The better and quicker compression rates also allow us to produce multiple daily backups of the full content in each and every hosting account, so if you delete anything by mistake, the last backup that we have will not be more than several hours old. This can be done because the backups take a lot less space and their generation is fast enough, so as to not affect the performance of our servers.
Data Compression in Semi-dedicated Hosting
The ZFS file system that runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It's one of the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data faster than the same data can be read from a hard drive if it were uncompressed. Thus, using LZ4 will speed up any site that runs on a platform where the algorithm is enabled. This high performance requires a lot of CPU processing time, that is provided by the numerous clusters working together as a part of our platform. In addition, LZ4 enables us to generate several backups of your content every day and have them for a month as they will take a reduced amount of space than standard backups and will be generated considerably faster without loading the servers.
