The term data compression describes lowering the number of bits of data that needs to be saved or transmitted. You can do this with or without the loss of data, so what will be removed throughout the compression shall be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the information and its quality will be identical, whereas in the second case the quality will be worse. You can find different compression algorithms that are more efficient for various sort of information. Compressing and uncompressing data frequently takes lots of processing time, therefore the server carrying out the action should have plenty of resources in order to be able to process the info quick enough. One 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 rather than storing the actual 1s and 0s.
Data Compression in Shared Website Hosting
The compression algorithm used by the ZFS file system that runs on our cloud web hosting platform is named LZ4. It can improve the performance of any site hosted in a shared website hosting account with us since not only does it compress data much better than algorithms employed by other file systems, but also uncompresses data at speeds that are higher than the HDD reading speeds. This is achieved by using a lot of CPU processing time, which 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 allows us to generate backup copies at a higher speed and on lower disk space, so we can have multiple daily backups of your files and databases and their generation won't change the performance of the servers. In this way, we can always recover all the content that you could have deleted by accident.
Data Compression in Semi-dedicated Hosting
The ZFS file system that runs on the cloud platform where your semi-dedicated hosting 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'll uncompress data much faster than the same data can be read from a hard disk drive if it were uncompressed. Thus, using LZ4 will quicken any website that runs on a platform where this algorithm is enabled. This high performance requires a lot of CPU processing time, which 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 backup copies of your content every day and save them for a month as they will take much less space than standard backups and will be created much quicker without loading the servers.
