Data compression is the compacting of information by reducing the number of bits which are stored or transmitted. Because of this, the compressed information takes considerably less disk space than the initial one, so additional content could be stored on identical amount of space. There are various compression algorithms which work in different ways and with many of them only the redundant bits are deleted, therefore once the data is uncompressed, there's no decrease in quality. Others remove unneeded bits, but uncompressing the data later will lead to reduced quality compared to the original. Compressing and uncompressing content requires a significant amount of system resources, particularly CPU processing time, so any hosting platform which uses compression in real time should have enough power to support this feature. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of saving the entire code.

Data Compression in Shared Hosting

The compression algorithm which we employ on the cloud web hosting platform where your new shared hosting account will be created is named LZ4 and it is applied by the state-of-the-art ZFS file system that powers the system. The algorithm is much better than the ones other file systems work with as its compression ratio is higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed since this happens quicker than data can be read from a hard disk drive. As a result, LZ4 improves the performance of every website stored on a server which uses this algorithm. We use LZ4 in an additional 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 thirty days. Not only do our backup copies take less space, but in addition their generation does not slow the servers down like it often happens with alternative file systems.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account shall be created on a cloud platform which runs on the advanced ZFS file system. The aforementioned uses a compression algorithm called LZ4, which is significantly better than 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 drive. Because of this websites running on a platform that uses LZ4 compression perform better since the algorithm is most effective 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 take much less space and they are generated faster, which allows us to have a couple of daily backups of your files and databases.
