Data compression is the compacting of data by reducing the number of bits which are stored or transmitted. Consequently, the compressed info will take much less disk space than the initial one, so more content could be stored on the same amount of space. There're various compression algorithms that function in different ways and with a number of them just the redundant bits are erased, which means that once the info is uncompressed, there is no loss of quality. Others erase unnecessary bits, but uncompressing the data later will lead to lower quality in comparison with the original. Compressing and uncompressing content takes a huge amount of system resources, in particular CPU processing time, so each and every Internet hosting platform which uses compression in real time needs to have sufficient power to support that attribute. 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 keeping the entire code.

Data Compression in Shared Hosting

The compression algorithm that we use on the cloud hosting platform where your new shared hosting account shall be created is named LZ4 and it is used by the advanced ZFS file system which powers the system. The algorithm is superior to the ones other file systems work with because its compression ratio is a lot higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed as this happens quicker than info can be read from a hard disk. Therefore, LZ4 improves the performance of each website hosted on a server that uses the algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio let us produce a couple of daily backup copies of the full content of all accounts and store them for 30 days. Not only do these backups take less space, but their generation will not slow the servers down like it can often happen 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's one of the best algorithms out there and definitely the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it'll uncompress data at a higher speed than the same data can be read from a hard drive if it were uncompressed. That way, using LZ4 will boost every Internet site that runs on a platform where the algorithm is present. This high performance requires a lot of CPU processing time, that's provided by the numerous clusters working together as a part of our platform. In addition to that, LZ4 allows us to generate several backup copies of your content every day and save them for a month as they will take much less space than regular backups and will be created considerably quicker without loading the servers.
