The term data compression describes lowering the number of bits of information that needs to be saved or transmitted. This can be achieved with or without the loss of information, so what will be removed throughout the compression will be either redundant data or unneeded one. When the data is uncompressed subsequently, in the first case the data and the quality will be identical, whereas in the second case the quality will be worse. There're various compression algorithms which are better for different sort of info. Compressing and uncompressing data frequently takes plenty of processing time, so the server carrying out the action must have sufficient resources to be able to process the data 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 in the binary code instead of storing the actual 1s and 0s.
Data Compression in Website Hosting
The compression algorithm used by the ZFS file system which runs on our cloud web hosting platform is called LZ4. It can supercharge the performance of any website hosted in a website hosting
account on our end because not only does it compress data more effectively than algorithms used by various file systems, but it also uncompresses data at speeds which are higher than the hard disk drive reading speeds. This is achieved by using a lot of CPU processing time, that 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 backup copies more speedily and on lower disk space, so we can have a couple of daily backups of your files and databases and their generation will not change the performance of the servers. This way, we could always restore all the content that you may have removed by mistake.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server
account will be created on a cloud platform that runs on the leading-edge ZFS file system. The latter uses a compression algorithm called LZ4, that is significantly better than alternative algorithms in terms of compression ratio and speed. The gain is apparent particularly when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. That is why Internet sites running on a platform which uses LZ4 compression perform faster as the algorithm is most efficient when it processes compressible data i.e. web content. One more advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need less space and they are generated faster, which enables us to have a number of daily backups of your files and databases.
