Data compression is the compacting of info by decreasing the number of bits which are stored or transmitted. Because of this, the compressed info takes much less disk space than the original one, so additional content might be stored on the same amount of space. You'll find various compression algorithms which function in different ways and with a lot of them only the redundant bits are erased, therefore once the data is uncompressed, there's no loss of quality. Others delete excessive bits, but uncompressing the data at a later time will result in lower quality compared to the original. Compressing and uncompressing content consumes a huge amount of system resources, and in particular CPU processing time, therefore each and every Internet hosting platform that employs compression in real time must have adequate power to support this feature. An example how information can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of keeping the whole code.

Data Compression in Hosting

The ZFS file system which operates on our cloud Internet hosting platform uses a compression algorithm identified as LZ4. The latter is considerably faster and better than any other algorithm you'll find, especially for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard disk drive, which improves the overall performance of websites hosted on ZFS-based platforms. As the algorithm compresses data very well and it does that quickly, we can generate several backup copies of all the content kept in the hosting accounts on our servers on a daily basis. Both your content and its backups will need less space and since both ZFS and LZ4 work very quickly, the backup generation will not change the performance of the web servers where your content will be kept.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account shall be created on a cloud platform that runs on the leading-edge ZFS file system. The latter uses a compression algorithm named LZ4, that is significantly 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 a lot faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard drive. That is why Internet sites running on a platform which uses LZ4 compression perform better because the algorithm is most effective when it processes compressible data i.e. site content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need less space and they are generated a lot quicker, which allows us to keep several daily backups of all your files and databases.
