Data compression is the compacting of info by reducing the number of bits which are stored or transmitted. Because of this, the compressed info will require substantially less disk space than the original one, so extra content could be stored using identical amount of space. You can find many different compression algorithms which function in different ways and with some of them just the redundant bits are erased, therefore once the data is uncompressed, there's no loss of quality. Others remove unneeded bits, but uncompressing the data at a later time will lead to reduced quality compared to the original. Compressing and uncompressing content takes a large amount of system resources, especially CPU processing time, therefore every hosting platform that employs compression in real time should have ample power to support this feature. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many sequential 1s or 0s there should be instead of saving the entire code.
Data Compression in Web Hosting
The compression algorithm used by the ZFS file system which runs on our cloud hosting platform is called LZ4. It can enhance the performance of any website hosted in a web hosting account on our end as not only does it compress data more effectively than algorithms used by alternative file systems, but it uncompresses data at speeds that are higher than the HDD reading speeds. This can be done by using a great deal of CPU processing time, that is not a problem for our platform since it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to create backups more speedily and on less disk space, so we will have multiple daily backups of your files and databases and their generation will not affect the performance of the servers. This way, we can always recover any content that you could have erased by mistake.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account shall be created on a cloud platform which is run on the leading-edge ZFS file system. The latter uses a compression algorithm called LZ4, that is far better than alternative algorithms in terms of compression ratio and speed. The gain is significant 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 hard disk. This is why Internet sites running on a platform which uses LZ4 compression perform faster because 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 that we keep take significantly less space and they are generated faster, which allows us to store a couple of daily backups of all your files and databases.
