Data compression is the compacting of data by decreasing the number of bits which are stored or transmitted. Consequently, the compressed data needs considerably less disk space than the initial one, so a lot more content could be stored on the same amount of space. You can find different compression algorithms that work in different ways and with many of them only the redundant bits are deleted, therefore once the information is uncompressed, there's no loss of quality. Others remove unnecessary bits, but uncompressing the data later will lead to lower quality in comparison with the original. Compressing and uncompressing content consumes a large amount of system resources, particularly CPU processing time, therefore every web hosting platform that uses compression in real time must have sufficient power to support this attribute. An example how information 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 keeping the actual code.

Data Compression in Hosting

The ZFS file system which is run on our cloud Internet hosting platform employs a compression algorithm called LZ4. The aforementioned is considerably faster and better than every other algorithm you'll find, especially for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data faster than it is read from a hard disk, which improves the performance of sites hosted on ZFS-based platforms. As the algorithm compresses data quite well and it does that very fast, we're able to generate several backups of all the content stored in the hosting accounts on our servers daily. Both your content and its backups will take reduced space and since both ZFS and LZ4 work very fast, the backup generation will not influence the performance of the hosting 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 that runs on the leading-edge ZFS file system. The aforementioned uses a compression algorithm named LZ4, that is much better than other algorithms when it comes to compression ratio and speed. The gain is noticeable particularly when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. This is why Internet sites running on a platform which employs LZ4 compression perform better since the algorithm is most effective when it processes compressible data i.e. website content. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep need significantly less space and they are generated quicker, which enables us to keep several daily backups of all your files and databases.
