The term data compression identifies reducing the number of bits of info that should be saved or transmitted. This can be done with or without losing info, which means that what will be deleted during the compression will be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the content and the quality shall be the same, whereas in the second case the quality shall be worse. You'll find various compression algorithms which are more effective for different sort of info. Compressing and uncompressing data in most cases takes a lot of processing time, so the server performing the action must 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 just how many consecutive positions should have 1 and just how many should have 0 in the binary code instead of storing the actual 1s and 0s.
Data Compression in Shared Hosting
The compression algorithm employed by the ZFS file system which runs on our cloud web hosting platform is called LZ4. It can upgrade the performance of any Internet site hosted in a shared hosting account on our end since not only does it compress data more efficiently than algorithms employed by alternative file systems, but it also uncompresses data at speeds that are higher than the hard disk reading speeds. This can be done by using a lot 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 make backups a lot faster and on less disk space, so we shall have several daily backups of your databases and files and their generation won't affect the performance of the servers. In this way, we could always recover any content that you may have deleted by accident.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account shall be created on a cloud platform that runs using the advanced ZFS file system. The latter uses a compression algorithm named LZ4, that is much better than alternative algorithms in terms of compression ratio and speed. The gain is noticeable particularly when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. Because of this sites running on a platform which employs LZ4 compression perform better as the algorithm is most efficient when it processes compressible data i.e. site content. One more advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep require significantly less space and they are generated faster, which allows us to keep a number of daily backups of your files and databases.
