The term data compression identifies decreasing the number of bits of info which should be saved or transmitted. This can be done with or without losing info, so what will be removed at the time of the compression shall be either redundant data or unnecessary one. When the data is uncompressed later on, in the first case the information and its quality shall be identical, while in the second case the quality will be worse. You'll find different compression algorithms which are better for different sort of information. Compressing and uncompressing data generally takes a lot of processing time, so the server executing the action should have sufficient resources to be able to process your data quick enough. An 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 instead of storing the particular 1s and 0s.

Data Compression in Shared Web Hosting

The compression algorithm employed by the ZFS file system which runs on our cloud web hosting platform is known as LZ4. It can boost the performance of any website hosted in a shared web hosting account with us as not only does it compress data more effectively than algorithms employed by various 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, which is not a problem for our platform because it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to create backups at a higher speed and on lower disk space, so we can have multiple daily backups of your databases and files and their generation will not change the performance of the servers. That way, we could always recover all of the content that you may have deleted by accident.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we provide are created on a powerful cloud platform which runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that is superior to any other algorithm you will find in terms of speed and data compression ratio when it comes to processing web content. This is valid particularly when data is uncompressed because LZ4 does that faster than it would be to read uncompressed data from a hard drive and as a result, websites running on a platform where LZ4 is present will function faster. We can take advantage of the feature despite of the fact that it needs quite a large amount of CPU processing time as our platform uses a wide range of powerful servers working together and we do not create accounts on a single machine like most companies do. There's an additional benefit of using LZ4 - considering that it compresses data really well and does that extremely fast, we can also make multiple daily backup copies of all accounts without affecting the performance of the servers and keep them for a month. That way, you'll always be able to bring back any content that you erase by accident.
