Data compression is the decrease of the number of bits which should be saved or transmitted and this particular process is very important in the internet hosting field due to the fact that information filed on hard drives is generally compressed in order to take less space. There're different algorithms for compressing data and they have different effectiveness depending on the content. Many of them remove only the redundant bits, so that no data will be lost, while others delete unnecessary bits, which results in worse quality once the particular data is uncompressed. The process requires plenty of processing time, which means that a web hosting server should be powerful enough in order to be able to compress and uncompress data right away. An example how binary code may be compressed is by "remembering" that there are five sequential 1s, for example, as an alternative to storing all five 1s.
Data Compression in Website Hosting
The compression algorithm that we work with on the cloud hosting platform where your new website hosting account shall be created is called LZ4 and it is applied by the leading-edge ZFS file system which powers the platform. The algorithm is greater than the ones other file systems work with as its compression ratio is higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed since this happens faster than information can be read from a hard drive. Therefore, LZ4 improves the performance of any site located on a server which uses this algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio let us produce several daily backup copies of the entire content of all accounts and keep them for a month. Not only do the backup copies take less space, but in addition their generation won't slow the servers down like it can often happen with alternative file systems.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account will be created on a cloud platform which is run on the innovative ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that's a lot better than all other algorithms regarding compression ratio and speed. The gain is noticeable particularly when data is being uncompressed and not only is LZ4 a lot faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. This is the reason why Internet sites running on a platform that uses LZ4 compression perform better as the algorithm is most efficient when it processes compressible data i.e. web content. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep take a lot less space and they are generated a lot faster, which enables us to have multiple daily backups of your files and databases.
