Data compression is the reduction of the number of bits that have to be saved or transmitted and this process is really important in the web hosting field because info kept on hard disks is usually compressed in order to take less space. You will find many different algorithms for compressing information and they provide different efficiency based upon the content. A number of them remove just the redundant bits, so that no data can be lost, while others remove unneeded bits, which leads to worse quality when the data is uncompressed. This method uses a lot of processing time, therefore a web hosting server should be powerful enough to be able to compress and uncompress data right away. One example how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, in contrast to storing all five 1s.
Data Compression in Website Hosting
The compression algorithm which we use on the cloud internet hosting platform where your new website hosting account will be created is known as LZ4 and it's used by the state-of-the-art ZFS file system that powers the platform. The algorithm is superior to the ones other file systems work with as its compression ratio is much higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed since this happens quicker than information can be read from a hard disk drive. Because of this, LZ4 improves the performance of any website stored on a server that uses this algorithm. We use LZ4 in one more way - its speed and compression ratio let us generate a number of daily backups of the whole content of all accounts and store them for one month. Not only do the backups take less space, but also their generation won't slow the servers down like it often happens with various other file systems.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account shall be created on a cloud platform which runs using the leading-edge ZFS file system. The latter uses a compression algorithm known as LZ4, which is much better than other algorithms when it comes to compression ratio and speed. The gain is visible especially 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 disk drive. This is the reason why sites running on a platform which uses LZ4 compression perform faster since the algorithm is most efficient when it processes compressible data i.e. site content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep require a lot less space and they're generated a lot quicker, which allows us to have a number of daily backups of your files and databases.
