The term data compression means lowering the number of bits of info that should be stored or transmitted. This can be achieved with or without losing data, which means that what will be deleted during 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 will be the same, while in the second case the quality shall be worse. You can find different compression algorithms which are more effective for different type of data. Compressing and uncompressing data generally takes lots of processing time, so the server performing the action needs to have adequate resources in order to be able to process your data 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 Web Hosting

The compression algorithm used by the ZFS file system that runs on our cloud internet hosting platform is called LZ4. It can improve the performance of any site hosted in a web hosting account with us since not only does it compress data much better than algorithms employed by other file systems, but it uncompresses data at speeds which are higher than the hard disk drive reading speeds. This is achieved by using a lot of CPU processing time, which is not a problem for our platform owing to the fact that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it allows us to make backup copies a lot faster and on lower disk space, so we can have a couple of daily backups of your files and databases and their generation will not change the performance of the servers. This way, we can always recover all content that you could have erased by accident.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform which runs on the innovative ZFS file system. The aforementioned uses a compression algorithm named LZ4, that is much better than all other algorithms regarding compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a HDD. This is the reason why Internet sites running on a platform that employs LZ4 compression perform faster as the algorithm is most effective when it processes compressible data i.e. site content. An additional advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep take a lot less space and they are generated a lot faster, which enables us to have multiple daily backups of your files and databases.
