The term data compression identifies decreasing the number of bits of data which has to be saved or transmitted. You can do this with or without the loss of info, so what will be deleted in the course of the compression will be either redundant data or unneeded 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 will be worse. You can find different compression algorithms which are better for different sort of info. Compressing and uncompressing data generally takes plenty of processing time, which means that the server carrying out the action should have enough resources to be able to process the data fast enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and how many should have 0 in the binary code instead of storing the particular 1s and 0s.
Data Compression in Web Hosting
The compression algorithm employed by the ZFS file system which runs on our cloud internet hosting platform is named LZ4. It can improve the performance of any site hosted in a web hosting account on our end because not only does it compress data more effectively than algorithms employed by various other file systems, but 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 for the reason that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it allows us to create backups more speedily and on less disk space, so we shall 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 can always recover the content that you may have removed by mistake.
Data Compression in Semi-dedicated Servers
The ZFS file system that runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It's one of 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 at a faster rate than the same data can be read from a hard disk drive if it were uncompressed. Thus, using LZ4 will accelerate any Internet site that runs on a platform where this algorithm is enabled. This high performance requires lots of CPU processing time, which is provided by the large number of clusters working together as a part of our platform. In addition, LZ4 makes it possible for us to generate several backups of your content every day and keep them for a month as they'll take a smaller amount of space than regular backups and will be created much quicker without loading the servers.
