The term data compression identifies lowering the number of bits of info that needs to be stored or transmitted. This can be done with or without the loss of info, which means that what will be deleted throughout the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the information and the quality shall be the same, whereas in the second case the quality will be worse. You will find different compression algorithms which are more efficient for different sort of info. Compressing and uncompressing data usually takes a lot of processing time, which means that the server carrying out the action must have ample resources to be able to process your info quick enough. One simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 inside the binary code instead of storing the particular 1s and 0s.
Data Compression in Hosting
The ZFS file system that runs on our cloud hosting platform employs a compression algorithm named LZ4. The latter is substantially faster and better than any other algorithm you will find, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard disk, which improves the performance of Internet sites hosted on ZFS-based platforms. Since the algorithm compresses data really well and it does that quickly, we can generate several backups of all the content stored in the hosting accounts on our servers on a daily basis. Both your content and its backups will take less space and since both ZFS and LZ4 work very quickly, the backup generation will not affect the performance of the web servers where your content will be stored.
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 among the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it will uncompress data quicker than the same data can be read from a hard disk drive if it were uncompressed. Thus, using LZ4 will boost any kind of Internet site that runs on a platform where this algorithm is present. The high performance requires plenty of CPU processing time, that's provided by the large number of clusters working together as a part of our platform. Furthermore, LZ4 allows us to generate several backup copies of your content every day and have them for one month as they will take much less space than regular backups and will be created considerably quicker without loading the servers.
