Data compression is the compacting of information by reducing the number of bits which are stored or transmitted. In this way, the compressed info needs substantially less disk space than the original one, so more content could be stored on identical amount of space. You will find many different compression algorithms that function in different ways and with several of them just the redundant bits are erased, so once the info is uncompressed, there's no decrease in quality. Others erase unnecessary bits, but uncompressing the data following that will result in reduced quality compared to the original. Compressing and uncompressing content consumes a huge amount of system resources, and in particular CPU processing time, therefore any hosting platform which employs compression in real time needs to have enough power to support that feature. An example how info can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" how many consecutive 1s or 0s there should be instead of keeping the actual code.

Data Compression in Web Hosting

The ZFS file system that is run on our cloud web hosting platform uses a compression algorithm named LZ4. The latter is a lot faster and better than every other algorithm you can find, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the performance of sites hosted on ZFS-based platforms. Because the algorithm compresses data quite well and it does that very fast, we are able to generate several backups of all the content stored in the web hosting accounts on our servers daily. Both your content and its backups will take less space and since both ZFS and LZ4 work very quickly, the backup generation will not affect the performance of the hosting servers where your content will be kept.

Data Compression in Semi-dedicated Hosting

The ZFS file system that runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It's among the best algorithms out there and definitely the best 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. Thus, using LZ4 will boost any site that runs on a platform where the algorithm is enabled. The high performance requires plenty of CPU processing time, that's provided by the numerous clusters working together as part of our platform. In addition, LZ4 allows us to generate several backups of your content every day and save them for a month as they will take a smaller amount of space than standard backups and will be created considerably faster without loading the servers.
