Data compression is the lowering of the number of bits which need to be saved or transmitted and the process is quite important in the web hosting field as information located on hard drives is often compressed to take less space. You can find different algorithms for compressing information and they offer different efficiency based on the content. A lot of them remove just the redundant bits, so that no data can be lost, while others remove unnecessary bits, which leads to worse quality when the data is uncompressed. The method requires plenty of processing time, therefore a web hosting server has to be powerful enough so as to be able to compress and uncompress data instantly. An example how binary code could be compressed is by "remembering" that there are five consecutive 1s, for example, in contrast to storing all five 1s.
Data Compression in Hosting
The compression algorithm that we use on the cloud hosting platform where your new hosting account shall be created is known as LZ4 and it's used by the revolutionary ZFS file system that powers the system. The algorithm is more advanced than the ones other file systems work with because its compression ratio is much higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed as this happens even faster than information can be read from a hard drive. For that reason, LZ4 improves the performance of any website located on a server which uses the algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio let us produce a number of daily backups of the full content of all accounts and store them for a month. Not only do our backup copies take less space, but also their generation will not slow the servers down like it often happens with some other file systems.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account will be created on a cloud platform that is run on the innovative ZFS file system. The aforementioned uses a compression algorithm named LZ4, that is a lot better than all other algorithms regarding compression ratio and speed. The gain is apparent particularly when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk. Because of this websites running on a platform which uses LZ4 compression perform faster as the algorithm is most effective when it processes compressible data i.e. website content. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take a lot less space and are generated a lot quicker, which allows us to have a number of daily backups of your files and databases.
