Data compression is the compacting of information by lowering the number of bits which are stored or transmitted. In this way, the compressed information will take considerably less disk space than the original one, so extra content can be stored using identical amount of space. There are many different compression algorithms that work in different ways and with many of them just the redundant bits are removed, which means that once the info is uncompressed, there's no loss of quality. Others erase excessive bits, but uncompressing the data afterwards will lead to reduced quality in comparison with the original. Compressing and uncompressing content takes a large amount of system resources, in particular CPU processing time, therefore each and every Internet hosting platform that employs compression in real time needs to have enough power to support this attribute. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of keeping the entire code.

Data Compression in Shared Website Hosting

The compression algorithm used by the ZFS file system that runs on our cloud hosting platform is called LZ4. It can upgrade the performance of any Internet site hosted in a shared website hosting account on our end because not only does it compress data more efficiently than algorithms used by other file systems, but it also uncompresses data at speeds that are higher than the hard disk reading speeds. This is achieved by using a great deal of CPU processing time, which is not a problem for our platform for the reason that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to generate backup copies faster and on lower disk space, so we can have several daily backups of your databases and files and their generation will not influence the performance of the servers. In this way, we can always restore all of the content that you could have removed by mistake.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account will be created on a cloud platform that runs on the advanced ZFS file system. The latter uses a compression algorithm known as LZ4, that's significantly better than various other algorithms with regard to compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also quicker 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 better because the algorithm is most efficient when it processes compressible data i.e. web content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep require much less space and are generated faster, which allows us to store a couple of daily backups of your files and databases.
