Data compression is the compacting of info by decreasing the number of bits which are stored or transmitted. Thus, the compressed info will need much less disk space than the original one, so additional content might be stored using identical amount of space. There're different compression algorithms that work in different ways and with several of them only the redundant bits are deleted, so once the info is uncompressed, there's no decrease in quality. Others remove unneeded bits, but uncompressing the data afterwards will lead to reduced quality in comparison with the original. Compressing and uncompressing content takes a huge amount of system resources, especially CPU processing time, therefore each and every hosting platform that uses compression in real time should have ample 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" the number of consecutive 1s or 0s there should be instead of saving the whole code.

Data Compression in Shared Hosting

The cloud hosting platform where your shared hosting account shall be generated works by using the impressive ZFS file system. The LZ4 compression method which the latter uses is greater in various aspects, and not only does it compress data better than any compression method that a number of other file systems use, but it's also considerably faster. The gains can be significant especially on compressible content like website files. Despite the fact that it may sound irrational, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk drive, so the performance of any Internet site hosted on our servers will be enhanced. The better and faster compression rates also allow us to make multiple daily backups of the full content in every single web hosting account, so in the event you delete something by mistake, the last back-up copy that we have will not be more than a few hours old. This can be done because the backups take significantly less space and their generation is quick enough, so as to not influence the performance of the servers.

Data Compression in Semi-dedicated Servers

The ZFS file system that runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It's among the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it will uncompress data much faster than the same data can be read from a hard drive if it were uncompressed. That way, using LZ4 will accelerate any Internet site that runs on a platform where the algorithm is enabled. This high performance requires a lot of CPU processing time, which is provided by the numerous clusters working together as part of our platform. Furthermore, LZ4 enables us to generate several backup copies of your content every day and have them for one month as they'll take much less space than typical backups and will be created much more quickly without loading the servers.
