Data compression is the compacting of info by decreasing the number of bits that are stored or transmitted. Thus, the compressed data requires less disk space than the initial one, so extra content could be stored on the same amount of space. There're different compression algorithms that work in different ways and with some of them only the redundant bits are deleted, therefore once the info is uncompressed, there's no loss of quality. Others remove unneeded bits, but uncompressing the data following that will lead to lower quality in comparison with the original. Compressing and uncompressing content requires a large amount of system resources, particularly CPU processing time, therefore every Internet hosting platform that uses compression in real time should have enough 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 storing the actual code.

Data Compression in Semi-dedicated Hosting

The semi-dedicated hosting plans which we provide are created on a powerful cloud platform that runs on the ZFS file system. ZFS works with a compression algorithm named LZ4 that is greater than any other algorithm you can find in terms of speed and data compression ratio when it comes to processing website content. This is valid particularly when data is uncompressed as LZ4 does that more rapidly 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 enabled will function faster. We are able to take full advantage of the feature despite of the fact that it requires quite a considerable amount of CPU processing time as our platform uses a lot of powerful servers working together and we don't make accounts on a single machine like many companies do. There is one more advantage of using LZ4 - considering the fact that it compresses data really well and does that speedily, we can also generate multiple daily backup copies of all accounts without influencing the performance of the servers and keep them for a whole month. By doing this, you'll always be able to bring back any content that you delete by accident.
