Data compression is the compacting of info by decreasing the number of bits which are stored or transmitted. As a result, the compressed info will take substantially less disk space than the initial one, so additional content can be stored using the same amount of space. You will find various compression algorithms which work in different ways and with many of them just the redundant bits are deleted, therefore once the information is uncompressed, there is no decrease in quality. Others remove unneeded bits, but uncompressing the data at a later time will lead to lower quality in comparison with the original. Compressing and uncompressing content requires a large amount of system resources, in particular CPU processing time, therefore each and every Internet hosting platform that uses compression in real time should have enough power to support this attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of saving the actual code.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account shall be created on a cloud platform that runs using the innovative ZFS file system. The aforementioned uses a compression algorithm named LZ4, that's much better than other algorithms in terms of compression ratio and speed. The gain is noticeable particularly when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also faster in uncompressing data than a system is in reading from a HDD. This is the reason why Internet sites running on a platform that uses LZ4 compression perform faster because the algorithm is most effective when it processes compressible data i.e. web content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep require less space and they're generated faster, which allows us to keep a couple of daily backups of your files and databases.
