The term data compression refers to lowering the number of bits of info that needs to be stored or transmitted. This can be achieved with or without the loss of information, which means that what will be deleted in the course of the compression can be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the information and the quality shall be the same, whereas in the second case the quality shall be worse. There are various compression algorithms that are better for various type of information. Compressing and uncompressing data often takes lots of processing time, which means that the server performing the action must have plenty of resources to be able to process your data quick 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 in the binary code rather than storing the particular 1s and 0s.

Data Compression in Shared Website Hosting

The compression algorithm employed by the ZFS file system that runs on our cloud web hosting platform is named LZ4. It can improve the performance of any website hosted in a shared website hosting account with us because not only does it compress info significantly better than algorithms used by alternative file systems, but it also 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 due to the fact that it uses clusters of powerful servers working together. A further advantage of LZ4 is that it enables us to create backup copies much more quickly and on lower disk space, so we shall have multiple daily backups of your databases and files and their generation won't change the performance of the servers. That way, we can always restore all content that you may have deleted by mistake.

Data Compression in Semi-dedicated Servers

The ZFS file system which runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It's among the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it will uncompress data quicker than the same data can be read from a hard drive if it were uncompressed. This way, using LZ4 will quicken every site that runs on a platform where this algorithm is enabled. The high performance requires lots of CPU processing time, that is provided by the great number of clusters working together as a part of our platform. In addition to that, LZ4 allows us to generate several backups of your content every day and keep them for one month as they'll take a smaller amount of space than regular backups and will be generated considerably quicker without loading the servers.
