Data compression is the compacting of data by lowering the number of bits that are stored or transmitted. Thus, the compressed info will need considerably less disk space than the original one, so additional content can be stored using identical amount of space. There are various compression algorithms that function in different ways and with a number of them just the redundant bits are erased, which means that once the data is uncompressed, there's no loss of quality. Others remove unnecessary bits, but uncompressing the data subsequently will result in reduced quality compared to the original. Compressing and uncompressing content consumes a significant amount of system resources, and in particular CPU processing time, so any hosting platform that uses compression in real time must have ample power to support this feature. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of saving the entire code.

Data Compression in Hosting

The ZFS file system which runs on our cloud web hosting platform uses a compression algorithm named LZ4. The aforementioned is a lot faster and better than any other algorithm available on the market, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data faster than it is read from a hard drive, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Due to the fact that the algorithm compresses data very well and it does that very fast, we are able to generate several backups 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 fast, the backup generation will not change the performance of the web hosting servers where your content will be kept.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform that runs on the advanced ZFS file system. The aforementioned uses a compression algorithm named LZ4, which is a lot better than other algorithms with regard to compression ratio and speed. The gain is noticeable particularly when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also quicker 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 as 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 take a lot less space and are generated a lot quicker, which enables us to keep a number of daily backups of all your files and databases.
