The term data compression identifies lowering the number of bits of info that should be saved or transmitted. This can be achieved with or without the loss of info, so what will be erased in the course of the compression can be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the info and the quality will be identical, while in the second case the quality will be worse. You will find various compression algorithms which are more efficient for various kind of data. Compressing and uncompressing data often takes plenty of processing time, so the server executing the action must have sufficient resources to be able to process the info fast enough. One simple example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 within the binary code instead of storing the actual 1s and 0s.

Data Compression in Shared Hosting

The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is named LZ4. It can supercharge the performance of any Internet site hosted in a shared hosting account on our end because not only does it compress info more effectively than algorithms used by other file systems, but it also uncompresses data at speeds which are higher than the hard drive reading speeds. This is achieved by using a great deal of CPU processing time, that is not a problem for our platform for the reason that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to generate backup copies more quickly and on less disk space, so we will have multiple daily backups of your databases and files and their generation won't affect the performance of the servers. This way, we could always restore all of the content that you may have erased by mistake.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform that runs using the innovative ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that's far better than all other algorithms with regard to compression ratio and speed. The gain is visible 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 drive. That's why websites running on a platform which uses LZ4 compression perform better as the algorithm is most effective when it processes compressible data i.e. website content. An additional advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep need a lot less space and are generated a lot quicker, which enables us to keep several daily backups of all your files and databases.
