Data compression is the compacting of information by decreasing the number of bits that are stored or transmitted. As a result, the compressed data will need substantially less disk space than the initial one, so a lot more content could be stored on the same amount of space. You will find many different compression algorithms that work in different ways and with several of them just the redundant bits are erased, which means that once the information is uncompressed, there is no decrease in quality. Others delete excessive bits, but uncompressing the data subsequently will result in reduced quality in comparison with the original. Compressing and uncompressing content consumes a large amount of system resources, especially CPU processing time, so each and every hosting platform which uses compression in real time should have ample power to support that feature. An example how information can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of saving the entire code.
Data Compression in Shared Web Hosting
The compression algorithm that we work with on the cloud hosting platform where your new shared web hosting account will be created is known as LZ4 and it is used by the revolutionary ZFS file system that powers the platform. The algorithm is much better than the ones other file systems employ since its compression ratio is much higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed since this happens faster than info can be read from a hard drive. As a result, LZ4 improves the performance of each and every site located on a server which uses the algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to generate several daily backup copies of the entire content of all accounts and store them for a month. Not only do the backups take less space, but also their generation does not slow the servers down like it can often happen with many other file systems.
Data Compression in Semi-dedicated Servers
Your semi-dedicated server account will be created on a cloud platform which is run on the innovative ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that is much better than alternative algorithms when it comes to compression ratio and speed. The gain is noticeable especially when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard drive. Because of this websites running on a platform that employs LZ4 compression perform faster as the algorithm is most effective when it processes compressible data i.e. website content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts which we keep need less space and are generated faster, which allows us to keep a couple of daily backups of your files and databases.
