Data compression is the compacting of data by lowering the number of bits which are stored or transmitted. As a result, the compressed info requires considerably less disk space than the initial one, so extra content can be stored on identical amount of space. You will find different compression algorithms that function in different ways and with a lot of them just the redundant bits are deleted, which means that once the info is uncompressed, there's no decrease in quality. Others erase excessive bits, but uncompressing the data following that will lead to reduced quality in comparison with the original. Compressing and uncompressing content needs a huge amount of system resources, especially CPU processing time, so every Internet hosting platform which employs compression in real time should have adequate power to support this attribute. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of keeping the actual code.

Data Compression in Shared Website Hosting

The compression algorithm used by the ZFS file system that runs on our cloud hosting platform is known as LZ4. It can enhance the performance of any site hosted in a shared website hosting account on our end because not only does it compress data significantly better than algorithms used by various other file systems, but it uncompresses data at speeds which 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 considering that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it enables us to generate backup copies more speedily and on reduced disk space, so we will have several daily backups of your files and databases and their generation won't influence the performance of the servers. This way, we can always recover all the content that you could have deleted by accident.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform that runs using the innovative ZFS file system. The latter uses a compression algorithm called LZ4, that's a lot better than all other algorithms with regard to compression ratio and speed. The gain is apparent 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. That is why sites running on a platform which uses LZ4 compression perform faster as the algorithm is most effective when it processes compressible data i.e. site content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep take much less space and are generated a lot quicker, which enables us to store several daily backups of your files and databases.
