The term data compression refers to lowering the number of bits of information which should be stored or transmitted. This can be achieved with or without the loss of info, which means that what will be erased in the course of the compression shall be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the information and its quality shall be the same, while in the second case the quality will be worse. There're various compression algorithms that are more efficient for different type of data. Compressing and uncompressing data normally takes a lot of processing time, therefore the server carrying out the action must have adequate resources to be able to process your data fast enough. A simple example how information can be compressed is to store how many consecutive positions should have 1 and just how many should have 0 in the binary code rather than storing the actual 1s and 0s.

Data Compression in Shared Hosting

The compression algorithm that we employ on the cloud internet hosting platform where your new shared hosting account will be created is called LZ4 and it's used by the leading-edge ZFS file system which powers the system. The algorithm is a lot better than the ones other file systems use because its compression ratio is much higher and it processes data a lot quicker. The speed is most noticeable when content is being uncompressed since this happens quicker than info can be read from a hdd. As a result, LZ4 improves the performance of each and every site hosted on a server that uses this particular algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to produce a number of daily backups of the whole content of all accounts and keep them for a month. Not only do these backups take less space, but in addition their generation doesn't slow the servers down like it often happens with many other file systems.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans that we provide are created on a powerful cloud platform that runs on the ZFS file system. ZFS employs a compression algorithm named LZ4 that outperforms any other algorithm on the market in terms of speed and data compression ratio when it comes to processing website content. This is valid especially when data is uncompressed because LZ4 does that a lot faster than it would be to read uncompressed data from a hard disk drive and for that reason, sites running on a platform where LZ4 is present will work faster. We are able to take full advantage of this feature although it requires quite a considerable amount of CPU processing time as our platform uses a wide range of powerful servers working together and we do not create accounts on a single machine like many companies do. There is an additional reward of using LZ4 - given that it compresses data really well and does that speedily, we can also generate several daily backup copies of all accounts without influencing the performance of the servers and keep them for an entire month. By doing this, you'll always be able to recover any content that you delete by accident.
