Data compression is the compacting of info by lowering the number of bits which are stored or transmitted. This way, the compressed information will require less disk space than the original one, so extra content might be stored using identical amount of space. There're various compression algorithms which work in different ways and with a number of them only the redundant bits are deleted, so once the data is uncompressed, there is no decrease in quality. Others delete excessive bits, but uncompressing the data following that will result in reduced quality in comparison with the original. Compressing and uncompressing content needs a significant amount of system resources, particularly CPU processing time, so every web hosting platform which uses compression in real time should 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" what number of consecutive 1s or 0s there should be instead of saving the entire code.

Data Compression in Shared Website Hosting

The compression algorithm that we use on the cloud hosting platform where your new shared website hosting account shall be created is called LZ4 and it is applied by the cutting-edge ZFS file system that powers the system. The algorithm is a lot better than the ones other file systems work with because its compression ratio is higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed since this happens faster than information can be read from a hard disk drive. Because of this, LZ4 improves the performance of every website hosted on a server that uses the algorithm. We use LZ4 in an additional way - its speed and compression ratio make it possible for us to produce a number of daily backups of the full content of all accounts and keep them for a month. Not only do our backup copies take less space, but also their generation will not slow the servers down like it often happens with some other file systems.

Data Compression in Semi-dedicated Hosting

The ZFS file system which runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It is one of the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it'll uncompress data quicker than the same data can be read from a hard disk drive if it were uncompressed. In this way, using LZ4 will speed up any website that runs on a platform where the algorithm is present. This high performance requires lots of CPU processing time, that's provided by the multitude of clusters working together as a part of our platform. In addition, LZ4 allows us to generate several backup copies of your content every day and save them for one month as they'll take a reduced amount of space than standard backups and will be created much quicker without loading the servers.
