Data compression is the compacting of info by reducing the number of bits that are stored or transmitted. As a result, the compressed information needs much less disk space than the original one, so additional content can be stored using identical amount of space. There are different compression algorithms that work in different ways and with a lot of them only the redundant bits are removed, therefore once the info is uncompressed, there's no loss of quality. Others erase excessive bits, but uncompressing the data later will result in lower quality compared to the original. Compressing and uncompressing content needs a significant amount of system resources, and in particular CPU processing time, so any hosting platform that employs compression in real time must have adequate power to support this attribute. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" the number of consecutive 1s or 0s there should be instead of saving the actual code.

Data Compression in Shared Website Hosting

The ZFS file system that operates on our cloud hosting platform employs a compression algorithm called LZ4. The aforementioned is a lot faster and better than any other algorithm you will find, particularly for compressing and uncompressing non-binary data i.e. internet content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the overall performance of websites hosted on ZFS-based platforms. As the algorithm compresses data very well and it does that very quickly, we are able to generate several backup copies of all the content stored in the shared website hosting accounts on our servers on a daily basis. Both your content and its backups will need reduced space and since both ZFS and LZ4 work very quickly, the backup generation will not change the performance of the hosting servers where your content will be stored.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans that we provide are created on a powerful cloud hosting platform that runs on the ZFS file system. ZFS uses a compression algorithm called LZ4 that outperforms any other algorithm available 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 because of this, websites running on a platform where LZ4 is present will function faster. We're able to take full advantage of this feature although it needs quite a lot of CPU processing time because our platform uses a wide range of powerful servers working together and we never make accounts on just a single machine like the majority of companies do. There is a further advantage of using LZ4 - considering the fact that it compresses data really well and does that very quickly, we can also generate several daily backups of all accounts without affecting the performance of the servers and keep them for a month. By doing this, you can always recover any content that you delete by accident.
