Data compression is the compacting of information by decreasing the number of bits which are stored or transmitted. In this way, the compressed information requires less disk space than the initial one, so more content could be stored using the same amount of space. You will find different compression algorithms which work in different ways and with several of them just the redundant bits are erased, so once the data is uncompressed, there is no decrease in quality. Others erase unneeded bits, but uncompressing the data at a later time will result in reduced quality compared to the original. Compressing and uncompressing content requires a large amount of system resources, and in particular CPU processing time, so every web hosting platform that employs compression in real time needs to have sufficient power to support this attribute. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of saving the entire code.
Data Compression in Shared Website Hosting
The compression algorithm which we use on the cloud web hosting platform where your new shared website hosting
account will be created is known as LZ4 and it's applied by the revolutionary 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 much higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed since this happens faster than data can be read from a hard drive. For that reason, LZ4 improves the performance of each and every Internet site located on a server which uses the algorithm. We use LZ4 in one more way - its speed and compression ratio make it possible for us to make multiple daily backups of the entire content of all accounts and store them for one month. Not only do our backup copies take less space, but in addition their generation won't slow the servers down like it often happens with many 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 will uncompress data much faster than the same data can be read from a hard disk drive if it were uncompressed. This way, using LZ4 will quicken any kind of website that runs on a platform where this algorithm is present. This high performance requires plenty of CPU processing time, which is provided by the large number of clusters working together as a part of our platform. Furthermore, LZ4 allows us to generate several backups of your content every day and keep them for a month as they'll take a reduced amount of space than typical backups and will be created considerably quicker without loading the servers.
