The term data compression describes decreasing the number of bits of information that needs to be stored or transmitted. This can be done with or without losing info, which means that what will be deleted in the course of the compression shall be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the info and the quality will be identical, while in the second case the quality shall be worse. You can find different compression algorithms that are better for various kind of info. Compressing and uncompressing data usually takes lots of processing time, so the server executing the action should have adequate resources in order to be able to process the data quick enough. A simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 within the binary code rather than storing the actual 1s and 0s.

Data Compression in Shared Web Hosting

The compression algorithm that we work with on the cloud web hosting platform where your new shared web hosting account shall be created is named LZ4 and it's used by the state-of-the-art ZFS file system which powers the platform. The algorithm is more advanced than the ones other file systems work with since its compression ratio is much higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed since this happens even faster than info can be read from a hard disk. As a result, LZ4 improves the performance of each and every site stored on a server which uses this algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio let us generate several daily backups of the full content of all accounts and keep them for thirty days. Not only do these backup copies take less space, but their generation will not slow the servers down like it often happens with other file systems.

Data Compression in Semi-dedicated Hosting

The ZFS file system which runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It's among the best algorithms out there and definitely the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data faster than the same data can be read from a hard drive if it were uncompressed. That way, using LZ4 will quicken every Internet site that runs on a platform where the algorithm is present. The high performance requires a lot of CPU processing time, which is provided by the great number of clusters working together as part of our platform. Furthermore, LZ4 makes it possible for us to generate several backup copies of your content every day and save them for a month as they will take a reduced amount of space than typical backups and will be created much quicker without loading the servers.
