The term data compression describes decreasing the number of bits of data that has to be saved or transmitted. This can be achieved with or without losing data, so what will be erased during the compression shall be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the data and its quality shall be identical, whereas in the second case the quality will be worse. There're various compression algorithms that are more effective for various sort of info. Compressing and uncompressing data generally takes plenty of processing time, so the server executing the action should have plenty of 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 just how many should have 0 inside the binary code rather than storing the particular 1s and 0s.

Data Compression in Shared Web Hosting

The compression algorithm employed by the ZFS file system which runs on our cloud hosting platform is called LZ4. It can supercharge the performance of any Internet site hosted in a shared web hosting account on our end since not only does it compress info more efficiently than algorithms used by various file systems, but also uncompresses data at speeds which are higher than the HDD reading speeds. This can be done by using a great deal of CPU processing time, which is not a problem for our platform due to the fact that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to make backups much more rapidly and on reduced disk space, so we will have several daily backups of your databases and files and their generation will not influence the performance of the servers. That way, we can always recover all of the content that you could have removed by mistake.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform which runs using the innovative ZFS file system. The aforementioned uses a compression algorithm known as LZ4, which is much better than all other algorithms when it comes to compression ratio and speed. The gain is apparent particularly when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk drive. That is why Internet sites running on a platform which uses LZ4 compression perform faster since the algorithm is most effective when it processes compressible data i.e. web content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need a lot less space and are generated faster, which allows us to have a couple of daily backups of all your files and databases.
