The term data compression means reducing the number of bits of information which should be stored or transmitted. This can be done with or without the loss of information, which means that 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 content and the quality will be identical, while in the second case the quality shall be worse. You can find various compression algorithms which are more efficient for different type of info. Compressing and uncompressing data usually takes plenty of processing time, therefore the server performing the action should have enough resources to be able to process the info quick enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 within the binary code as an alternative to storing the particular 1s and 0s.
Data Compression in Hosting
The compression algorithm that we work with on the cloud hosting platform where your new hosting account will be created is named LZ4 and it's used by the leading-edge ZFS file system that powers the system. The algorithm is greater than the ones other file systems work with as its compression ratio is a lot higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed as this happens quicker than info can be read from a hdd. As a result, LZ4 improves the performance of each website hosted on a server which uses this particular algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio allow us to make a couple of daily backup copies of the full content of all accounts and keep them for 30 days. Not only do these backup copies take less space, but also their generation doesn't slow the servers down like it can often happen with many other file systems.
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 web content, as its ratio is very high and it'll uncompress data at a higher speed than the same data can be read from a hard disk drive if it were uncompressed. That way, using LZ4 will quicken every Internet site that runs on a platform where this algorithm is present. This high performance requires lots of CPU processing time, that is provided by the large number of clusters working together as part of our platform. In addition to that, LZ4 makes it possible for us to generate several backups of your content every day and save them for one month as they'll take much less space than standard backups and will be generated much quicker without loading the servers.
