The term data compression means reducing the number of bits of information which has to be stored or transmitted. You can do this with or without losing information, which means that what will be erased at the time of the compression will be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the information and the quality shall be the same, whereas in the second case the quality will be worse. There are various compression algorithms that are more efficient for various sort of info. Compressing and uncompressing data normally takes a lot of processing time, so the server executing the action should have enough resources in order to be able to process the info quick enough. An example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 in the binary code as an alternative to storing the particular 1s and 0s.

Data Compression in Cloud Website Hosting

The compression algorithm employed by the ZFS file system that runs on our cloud web hosting platform is known as LZ4. It can improve the performance of any Internet site hosted in a cloud website hosting account on our end because not only does it compress info more efficiently than algorithms used by other file systems, but also uncompresses data at speeds which are higher than the hard drive reading speeds. This is achieved by using a lot of CPU processing time, that is not a problem for our platform for the reason that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to make backup copies more rapidly and on less disk space, so we can have a couple of daily backups of your files and databases and their generation will not influence the performance of the servers. This way, we can always recover all of the content that you may have removed by accident.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform which runs on the leading-edge ZFS file system. The latter uses a compression algorithm called LZ4, that's much better than various other algorithms in terms of compression ratio and speed. The gain is noticeable particularly when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard drive. That is why sites running on a platform which uses LZ4 compression perform better as the algorithm is most efficient when it processes compressible data i.e. website content. An additional advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep require significantly less space and they are generated faster, which enables us to store a couple of daily backups of all your files and databases.
