Data compression is the decrease of the number of bits that have to be saved or transmitted and the process is quite important in the web hosting field because information located on hard disks is often compressed so as to take less space. You'll find various algorithms for compressing data and they offer different effectiveness based upon the content. Some of them remove just the redundant bits, so no data will be lost, while others remove unneeded bits, which results in worse quality once your data is uncompressed. The process uses plenty of processing time, therefore an internet hosting server has to be powerful enough to be able to compress and uncompress data in real time. One example how binary code can be compressed is by "remembering" that there are five sequential 1s, for example, as an alternative to storing all five 1s.
Data Compression in Shared Web Hosting
The compression algorithm which we employ on the cloud hosting platform where your new shared web hosting
account will be created is called LZ4 and it is used by the leading-edge ZFS file system which powers the system. The algorithm is a lot better than the ones other file systems employ since 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 quicker than data can be read from a hard disk. As a result, LZ4 improves the performance of any website located on a server which uses this algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio let us produce multiple daily backup copies of the full content of all accounts and keep them for a month. Not only do our backups take less space, but also their generation will not slow the servers down like it often happens with various other file systems.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server
account will be created on a cloud platform which runs on the advanced ZFS file system. The latter uses a compression algorithm named LZ4, which is a lot better than all 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 faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard disk. This is why websites running on a platform which employs LZ4 compression perform better as the algorithm is most effective when it processes compressible data i.e. web content. An additional 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 quicker, which enables us to have a couple of daily backups of all your files and databases.
