The term data compression refers to decreasing the number of bits of information that should be saved or transmitted. You can do this with or without losing data, which means that what will be erased at the time of the compression will be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the data and its quality shall be identical, whereas in the second case the quality will be worse. There are different compression algorithms that are more effective for different kind of information. Compressing and uncompressing data generally takes a lot of processing time, therefore the server executing the action must have sufficient resources to be able to process your data fast 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 in the binary code instead of storing the particular 1s and 0s.
Data Compression in Hosting
The compression algorithm employed by the ZFS file system which runs on our cloud internet hosting platform is called LZ4. It can upgrade the performance of any site hosted in a hosting account with us because not only does it compress info significantly better than algorithms employed by various file systems, but it also uncompresses data at speeds that are higher than the HDD reading speeds. This can be done by using a lot of CPU processing time, which is not a problem for our platform since it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to create backups much quicker and on reduced disk space, so we will have a couple of daily backups of your databases and files and their generation won't influence the performance of the servers. That way, we could always recover the content that you could have removed by mistake.
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 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 boost every Internet site that runs on a platform where this algorithm is present. The high performance requires a lot of CPU processing time, that is provided by the numerous clusters working together as part of our platform. Furthermore, LZ4 allows us to generate several backup copies of your content every day and keep them for one month as they will take a smaller amount of space than typical backups and will be generated much quicker without loading the servers.
