The term data compression refers to lowering the number of bits of info which has to be stored or transmitted. This can be achieved with or without losing information, which means that what will be deleted at the time of the compression shall be either redundant data or unnecessary one. When the data is uncompressed afterwards, in the first case the data and its quality shall be identical, while in the second case the quality shall be worse. You'll find different compression algorithms that are more efficient for various sort of data. Compressing and uncompressing data usually takes plenty of processing time, so the server performing the action should have adequate resources to be able to process your data quick enough. One simple example how information can be compressed is to store how many sequential positions should have 1 and just how many should have 0 in the binary code instead of storing the actual 1s and 0s.

Data Compression in Shared Hosting

The compression algorithm that we work with on the cloud hosting platform where your new shared hosting account shall be created is known as LZ4 and it is applied by the exceptional ZFS file system that powers the system. The algorithm is superior to the ones other file systems use since its compression ratio is higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than data can be read from a hdd. Therefore, LZ4 improves the performance of every Internet site located on a server which uses this algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio let us make a couple of daily backup copies of the full content of all accounts and keep them for thirty days. Not only do these 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 Hosting

Your semi-dedicated hosting account shall be created on a cloud platform that is run on the leading-edge ZFS file system. The latter uses a compression algorithm known as LZ4, that's a lot better than all the other algorithms regarding compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. Because of this websites running on a platform which employs LZ4 compression perform better since the algorithm is most effective when it processes compressible data i.e. web content. An additional advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take less space and they're generated faster, which allows us to keep several daily backups of your files and databases.
