The term data compression means reducing the number of bits of data that needs to be saved or transmitted. You can do this with or without losing information, which means that what will be removed in the course of the compression can be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the info and the quality will be identical, whereas in the second case the quality shall be worse. There are different compression algorithms that are more efficient for various kind of information. Compressing and uncompressing data frequently takes plenty of processing time, which means that the server performing the action should have sufficient resources in order to be able to process your info fast enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and how many should have 0 in the binary code rather than storing the actual 1s and 0s.

Data Compression in Shared Web Hosting

The compression algorithm which we employ on the cloud hosting platform where your new shared web hosting account shall be created is named LZ4 and it is used by the state-of-the-art ZFS file system which powers the platform. The algorithm is superior to the ones other file systems employ as its compression ratio is higher and it processes data significantly quicker. The speed is most noticeable when content is being uncompressed since this happens quicker than data can be read from a hard disk. Because of this, LZ4 improves the performance of any Internet site stored on a server that uses this particular algorithm. We use LZ4 in one more way - its speed and compression ratio make it possible for us to produce a number of daily backup copies of the entire content of all accounts and keep them for thirty days. Not only do the backup copies take less space, but their generation doesn't slow the servers down like it often happens with some other file systems.

Data Compression in Semi-dedicated Hosting

Your semi-dedicated hosting account shall be created on a cloud platform which runs on the cutting-edge ZFS file system. The latter uses a compression algorithm called LZ4, that is a lot better than other algorithms in terms of compression ratio and speed. The gain is apparent particularly when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. That's why Internet sites running on a platform which employs LZ4 compression perform better as the algorithm is most effective when it processes compressible data i.e. web content. A further advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep need less space and they are generated a lot quicker, which allows us to keep a number of daily backups of all your files and databases.
