The term data compression identifies lowering the number of bits of info that should be stored or transmitted. You can do this with or without the loss of data, so what will be deleted in the course of the compression shall be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the content and the quality shall be identical, whereas in the second case the quality shall be worse. You'll find various compression algorithms that are better for various sort of data. Compressing and uncompressing data frequently takes a lot of processing time, so the server executing the action needs to have ample resources in order to be able to process the data quick enough. An 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 rather than storing the actual 1s and 0s.
Data Compression in Shared Website Hosting
The compression algorithm which we use on the cloud web hosting platform where your new shared website hosting account shall be created is named LZ4 and it's applied by the revolutionary ZFS file system that powers the system. The algorithm is better than the ones other file systems work with because its compression ratio is a lot higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed since this happens quicker than data can be read from a hard drive. For that reason, LZ4 improves the performance of each Internet site located on a server which uses this particular algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio let us generate a couple of daily backup copies of the full content of all accounts and keep them for one month. Not only do the backup copies take less space, but also their generation does not slow the servers down like it can often happen with many other file systems.
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 is one of the best algorithms out there and positively the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it'll uncompress data much faster than the same data can be read from a hard disk drive if it were uncompressed. In this way, using LZ4 will boost any kind of site that runs on a platform where this algorithm is enabled. The high performance requires plenty of CPU processing time, that is provided by the great number of clusters working together as part of our platform. What's more, LZ4 allows us to generate several backups of your content every day and save them for one month as they will take a smaller amount of space than standard backups and will be generated much quicker without loading the servers.
