The term data compression describes reducing the number of bits of data that has to be stored or transmitted. You can do this with or without losing data, which means that what will be erased throughout the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the information and the quality shall be identical, whereas in the second case the quality shall be worse. You will find different compression algorithms that are more effective for various type of info. Compressing and uncompressing data often takes a lot of processing time, so the server performing the action should have ample resources in order to be able to process your data fast 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 in the binary code rather than storing the particular 1s and 0s.
Data Compression in Shared Web Hosting
The compression algorithm used by the ZFS file system which runs on our cloud internet hosting platform is known as LZ4. It can boost the performance of any website hosted in a shared web hosting account with us since not only does it compress info more effectively than algorithms employed by various other file systems, but it also uncompresses data at speeds that are higher than the hard disk drive reading speeds. This is achieved by using a lot of CPU processing time, that is not a problem for our platform due to the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to generate backups faster and on lower disk space, so we shall have a couple of daily backups of your databases and files and their generation won't change the performance of the servers. This way, we can always restore all content that you could have deleted by mistake.
Data Compression in Semi-dedicated Servers
The semi-dedicated server plans which we provide are created on a powerful cloud platform which runs on the ZFS file system. ZFS employs a compression algorithm known as LZ4 that is superior to any other algorithm out there in terms of speed and compression ratio when it comes to processing web content. This is valid especially when data is uncompressed because LZ4 does that much faster than it would be to read uncompressed data from a hard disk and owing to this, websites running on a platform where LZ4 is enabled will work faster. We can take advantage of the feature despite of the fact that it requires quite a large amount of CPU processing time because our platform uses a wide range of powerful servers working together and we never make accounts on just a single machine like the vast majority of companies do. There's one more reward of using LZ4 - since it compresses data rather well and does that speedily, we can also make multiple daily backups of all accounts without affecting the performance of the servers and keep them for 30 days. That way, you will always be able to bring back any content that you delete by mistake.
