The term data compression refers to reducing the number of bits of data which needs to be saved or transmitted. This can be done with or without losing information, which means that what will be deleted throughout the compression shall 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, whereas in the second case the quality shall be worse. You will find various compression algorithms which are more effective for various kind of data. Compressing and uncompressing data in most cases takes plenty of processing time, therefore the server executing the action must have enough resources to be able to process the data fast enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 within the binary code rather than storing the particular 1s and 0s.

Data Compression in Cloud Web Hosting

The compression algorithm which we employ on the cloud hosting platform where your new cloud web hosting account shall be created is named LZ4 and it's used by the cutting-edge ZFS file system that powers the system. The algorithm is a lot better than the ones other file systems work with since its compression ratio is higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed as this happens more quickly than information can be read from a hard drive. For that reason, LZ4 improves the performance of every website hosted on a server that uses the algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio let us make multiple daily backup copies of the entire content of all accounts and keep them for 30 days. Not only do the backups take less space, but in addition their generation will not slow the servers down like it can often happen with various other file systems.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform which is run on the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that is a lot better than various other algorithms when it comes to compression ratio and speed. The gain is noticeable especially 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 disk drive. That is why Internet sites running on a platform that employs LZ4 compression perform faster as the algorithm is most efficient when it processes compressible data i.e. site content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep take significantly less space and are generated a lot faster, which enables us to keep a couple of daily backups of your files and databases.
