Data compression is the compacting of data by decreasing the number of bits which are stored or transmitted. In this way, the compressed information takes substantially less disk space than the original one, so extra content can be stored using identical amount of space. There're different compression algorithms that function in different ways and with many of them just the redundant bits are removed, so once the info is uncompressed, there is no decrease in quality. Others delete unnecessary bits, but uncompressing the data subsequently will result in lower quality compared to the original. Compressing and uncompressing content consumes a large amount of system resources, particularly CPU processing time, so each and every Internet hosting platform which employs compression in real time should have adequate power to support that attribute. An example how data can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of keeping the actual code.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account shall be created on a cloud platform which runs using the cutting-edge ZFS file system. The latter uses a compression algorithm known as LZ4, which is significantly better than all the other algorithms with regard to compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk drive. Because of this Internet sites running on a platform which employs LZ4 compression perform better as the algorithm is most effective when it processes compressible data i.e. site content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep take significantly less space and are generated quicker, which enables us to have multiple daily backups of all your files and databases.
