The term data compression describes decreasing the number of bits of data which should be stored or transmitted. This can be done with or without the loss of info, so what will be deleted in the course of the compression will be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the info and the quality shall be the same, whereas in the second case the quality will be worse. You will find various compression algorithms that are more effective for different kind of data. Compressing and uncompressing data normally takes plenty of processing time, so the server executing the action must have ample resources in order 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 rather than storing the actual 1s and 0s.
Data Compression in Shared Web Hosting
The compression algorithm that we use on the cloud internet hosting platform where your new shared web hosting account will be created is called LZ4 and it is applied by the advanced ZFS file system which powers the system. The algorithm is much better than the ones other file systems use because its compression ratio is a lot higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed as this happens faster than info can be read from a hard drive. Consequently, LZ4 improves the performance of any website hosted on a server that uses the algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio allow us to make a number of daily backups of the entire content of all accounts and keep them for thirty days. Not only do the backup copies take less space, but also their generation doesn't slow the servers down like it often happens with alternative file systems.
Data Compression in Semi-dedicated Servers
The ZFS file system that runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It's one of the best algorithms out there and positively the best one when it comes to compressing and uncompressing web content, as its ratio is very high and it will uncompress data quicker than the same data can be read from a hard drive if it were uncompressed. This way, using LZ4 will speed up any website that runs on a platform where this algorithm is present. The high performance requires plenty of CPU processing time, which is provided by the multitude of clusters working together as part of our platform. In addition, LZ4 makes it possible for us to generate several backups of your content every day and save them for a month as they will take a reduced amount of space than standard backups and will be generated considerably quicker without loading the servers.
