Data compression is the compacting of info by reducing the number of bits that are stored or transmitted. Because of this, the compressed data takes less disk space than the initial one, so extra content might be stored using the same amount of space. There're many different compression algorithms that work in different ways and with several of them just the redundant bits are deleted, so once the data is uncompressed, there's no loss of quality. Others delete unneeded bits, but uncompressing the data at a later time will lead to lower quality compared to the original. Compressing and uncompressing content consumes a huge amount of system resources, especially CPU processing time, therefore any Internet hosting platform which uses compression in real time needs to have enough power to support this feature. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many sequential 1s or 0s there should be instead of keeping the actual code.
Data Compression in Shared Hosting
The compression algorithm which we employ on the cloud hosting platform where your new shared hosting account will be created is called LZ4 and it is applied by the advanced ZFS file system which powers the platform. The algorithm is a lot better than the ones other file systems use as its compression ratio is higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed as this happens quicker than info can be read from a hard drive. As a result, LZ4 improves the performance of every website stored on a server which uses this algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio let us generate a couple of daily backup copies of the entire content of all accounts and keep them for thirty days. Not only do the backup copies take less space, but in addition their generation will not slow the servers down like it often happens with alternative file systems.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account shall be created on a cloud platform that runs on the state-of-the-art ZFS file system. The latter uses a compression algorithm known as LZ4, that is far better than other algorithms when it comes to compression ratio and speed. The gain is noticeable especially 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 drive. This is why Internet sites running on a platform that uses LZ4 compression perform better as the algorithm is most effective when it processes compressible data i.e. site content. Another advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep take much less space and they're generated quicker, which enables us to keep several daily backups of all your files and databases.
