The term data compression identifies reducing the number of bits of data which has to be stored or transmitted. You can do this with or without the loss of info, so what will be deleted at the time of the compression will be either redundant data or unneeded one. When the data is uncompressed afterwards, in the first case the data and the quality shall be the same, whereas in the second case the quality will be worse. You can find various compression algorithms which are better for different kind of info. Compressing and uncompressing data often takes lots of processing time, so the server carrying out the action needs to have ample resources to be able to process the data fast enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 within the binary code instead of storing the particular 1s and 0s.
Data Compression in Shared Website Hosting
The compression algorithm employed by the ZFS file system that runs on our cloud internet hosting platform is called LZ4. It can enhance the performance of any site hosted in a shared website hosting account with us as not only does it compress data more efficiently than algorithms employed by various other file systems, but also uncompresses data at speeds which are higher than the hard disk reading speeds. This can be done by using a great deal of CPU processing time, that 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 enables us to generate backups much quicker and on less disk space, so we will have a couple of daily backups of your files and databases and their generation won't change the performance of the servers. This way, we could always restore all content that you could have deleted by mistake.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account will be created on a cloud platform that is run on the leading-edge ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that is much better than all the other algorithms in terms of compression ratio and speed. The gain is visible 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 disk. Because of this Internet sites running on a platform which uses LZ4 compression perform better because the algorithm is most efficient when it processes compressible data i.e. site content. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep need less space and they are generated faster, which allows us to have several daily backups of your files and databases.
