The term data compression describes decreasing the number of bits of info which has to be stored or transmitted. You can do this with or without losing info, so what will be removed during the compression shall be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the content and its quality will be identical, whereas in the second case the quality will be worse. There're different compression algorithms which are more effective for different sort of data. Compressing and uncompressing data normally takes plenty of processing time, so the server performing the action needs to have sufficient resources to be able to process your info quick enough. A 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 as an alternative to storing the actual 1s and 0s.
Data Compression in Hosting
The compression algorithm used by the ZFS file system that runs on our cloud internet hosting platform is known as LZ4. It can upgrade the performance of any website hosted in a hosting account with us since not only does it compress data significantly better than algorithms employed by various file systems, but it uncompresses data at speeds which are higher than the hard disk drive reading speeds. This can be done by using a great deal of CPU processing time, that is not a problem for our platform considering the fact that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it allows us to generate backup copies at a higher speed and on reduced disk space, so we shall have several daily backups of your files and databases and their generation won't change the performance of the servers. That way, we could always recover the content that you could have removed by mistake.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account shall be created on a cloud platform that runs using the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm called LZ4, that's a lot better than other algorithms in terms of compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard drive. That's why Internet sites running on a platform that uses LZ4 compression perform better since the algorithm is most effective when it processes compressible data i.e. web content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep need a lot less space and are generated faster, which allows us to keep multiple daily backups of your files and databases.
