Data compression is the compacting of data by decreasing the number of bits that are stored or transmitted. As a result, the compressed data requires substantially less disk space than the original one, so much more content could be stored on the same amount of space. You can find various compression algorithms that work in different ways and with many of them only the redundant bits are removed, which means that once the information is uncompressed, there's no decrease in quality. Others remove excessive bits, but uncompressing the data later on will lead to reduced quality in comparison with the original. Compressing and uncompressing content takes a huge amount of system resources, and in particular CPU processing time, therefore any hosting platform which uses compression in real time must have adequate power to support this feature. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of storing the entire code.
Data Compression in Cloud Hosting
The ZFS file system which runs on our cloud hosting platform employs a compression algorithm named LZ4. The aforementioned is substantially faster and better than every other algorithm you'll find, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the overall performance of sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data very well and it does that very fast, we're able to generate several backup copies of all the content stored in the cloud hosting accounts on our servers daily. Both your content and its backups will take less space and since both ZFS and LZ4 work extremely fast, the backup generation will not affect the performance of the web servers where your content will be stored.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account shall be created on a cloud platform which is run on the innovative ZFS file system. The latter uses a compression algorithm called LZ4, that is much better than all other algorithms regarding compression ratio and speed. The gain is significant 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 drive. This is why sites running on a platform which employs LZ4 compression perform faster since the algorithm is most efficient when it processes compressible data i.e. web content. An additional advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take less space and are generated quicker, which enables us to store multiple daily backups of your files and databases.
