Data compression is the lowering of the number of bits that need to be stored or transmitted and this process is really important in the web hosting field as information stored on HDDs is typically compressed to take less space. There are various algorithms for compressing information and they have different effectiveness depending on the content. Many of them remove only the redundant bits, so no data will be lost, while others remove unnecessary bits, which leads to worse quality when the particular data is uncompressed. The process uses plenty of processing time, so a hosting server has to be powerful enough in order to be able to compress and uncompress data immediately. One example how binary code can be compressed is by "remembering" that there're five sequential 1s, for example, rather than storing all five 1s.
Data Compression in Hosting
The compression algorithm used by the ZFS file system that runs on our cloud web hosting platform is named LZ4. It can supercharge the performance of any Internet site hosted in a hosting
account on our end because not only does it compress data much better than algorithms used by alternative file systems, but it also uncompresses data at speeds that are higher than the hard disk drive reading speeds. This is achieved by using a great deal of CPU processing time, that is not a problem for our platform for the reason that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it enables us to make backup copies a lot faster and on reduced disk space, so we shall have multiple daily backups of your files and databases and their generation will not affect the performance of the servers. This way, we could always restore any kind of content that you may have removed by accident.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be created on a cloud platform that runs on the state-of-the-art ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that's significantly better than all the other algorithms when it comes to compression ratio and speed. The gain is noticeable particularly when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also faster in uncompressing data than a system is in reading from a HDD. That is why sites running on a platform that employs LZ4 compression perform faster because the algorithm is most efficient when it processes compressible data i.e. site content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take significantly less space and are generated faster, which enables us to store several daily backups of your files and databases.
