The term data compression means reducing the number of bits of data that has to be stored or transmitted. You can do this with or without losing info, so what will be removed throughout the compression will be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the content and the quality shall be the same, while in the second case the quality shall be worse. There're various compression algorithms which are more effective for different kind of data. Compressing and uncompressing data generally takes lots of processing time, so the server performing the action needs to have enough resources to be able to process your data quick enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 in the binary code as an alternative to storing the actual 1s and 0s.

Data Compression in Shared Web Hosting

The compression algorithm that we work with on the cloud internet hosting platform where your new shared web hosting account will be created is called LZ4 and it is used by the revolutionary ZFS file system that powers the system. The algorithm is far better than the ones other file systems employ 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 even faster than information can be read from a hdd. Consequently, LZ4 improves the performance of each website hosted on a server which uses this particular algorithm. We take advantage of LZ4 in an additional way - its speed and compression ratio let us generate multiple daily backup copies of the full content of all accounts and keep them for thirty days. Not only do the backup copies take less space, but also their generation will not slow the servers down like it often happens with 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 among the best algorithms out there and positively the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it can uncompress data a lot faster than the same data can be read from a hard drive if it were uncompressed. Thus, using LZ4 will quicken any kind of Internet site that runs on a platform where this algorithm is present. This high performance requires lots of CPU processing time, that's provided by the great number of clusters working together as part of our platform. What's more, LZ4 allows us to generate several backup copies of your content every day and save them for one month as they'll take much less space than typical backups and will be created much quicker without loading the servers.
