The term data compression describes reducing the number of bits of information which needs to be saved or transmitted. You can do this with or without the loss of data, which means that what will be removed throughout the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the data and the quality will be the same, while in the second case the quality will be worse. You can find different compression algorithms which are more effective for different kind of data. Compressing and uncompressing data generally takes plenty of processing time, which means that the server executing the action needs to have ample resources in order to be able to process your data quick enough. An example how information can be compressed is to store just how many sequential positions should have 1 and how many should have 0 inside the binary code rather than storing the actual 1s and 0s.

Data Compression in Shared Web Hosting

The compression algorithm that we work with on the cloud hosting platform where your new shared web hosting account shall be created is called LZ4 and it is used by the exceptional ZFS file system that powers the system. The algorithm is a lot better than the ones other file systems employ since its compression ratio is much higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens even faster than information can be read from a hard drive. As a result, LZ4 improves the performance of each site located on a server which uses this algorithm. We use LZ4 in one more way - its speed and compression ratio let us make several daily backup copies of the full content of all accounts and keep them for one month. Not only do the backup copies take less space, but in addition their generation will not slow the servers down like it can often happen with various other file systems.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we supply are created on a powerful cloud hosting platform which runs on the ZFS file system. ZFS works with a compression algorithm named LZ4 that is superior to any other algorithm on the market in terms of speed and compression ratio when it comes to processing website content. This is valid especially when data is uncompressed because LZ4 does that more quickly than it would be to read uncompressed data from a hard drive and owing to this, sites running on a platform where LZ4 is present will function at a higher speed. We are able to take full advantage of the feature despite of the fact that it requires quite a great deal of CPU processing time because our platform uses a huge number of powerful servers working together and we don't make accounts on a single machine like the vast majority of companies do. There is an additional benefit of using LZ4 - since it compresses data rather well and does that very quickly, we can also make multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for a month. In this way, you can always recover any content that you delete by mistake.
