Data compression is the compacting of information by decreasing the number of bits which are stored or transmitted. Because of this, the compressed information will need substantially less disk space than the initial one, so extra content could be stored using the same amount of space. There're many different compression algorithms that work in different ways and with a number of them only the redundant bits are deleted, therefore once the info is uncompressed, there's no loss of quality. Others erase excessive bits, but uncompressing the data later will lead to lower quality in comparison with the original. Compressing and uncompressing content requires a huge amount of system resources, and in particular CPU processing time, so any web hosting platform that employs compression in real time must have ample power to support this feature. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many sequential 1s or 0s there should be instead of keeping the whole code.
Data Compression in Website Hosting
The compression algorithm that we use on the cloud internet hosting platform where your new website hosting account will be created is known as LZ4 and it's applied by the cutting-edge ZFS file system which powers the platform. The algorithm is a lot better than the ones other file systems employ because its compression ratio is a lot higher and it processes data considerably quicker. The speed is most noticeable when content is being uncompressed as this happens even faster than info can be read from a hard drive. For that reason, LZ4 improves the performance of each and every Internet site located on a server which uses this particular algorithm. We take full advantage of LZ4 in an additional way - its speed and compression ratio allow us to make a number of daily backups of the whole content of all accounts and store them for a month. Not only do our backups take less space, but their generation doesn't slow the servers down like it often happens with various other file systems.
Data Compression in Semi-dedicated Hosting
The semi-dedicated hosting plans that we offer are created on a powerful cloud platform that runs on the ZFS file system. ZFS employs a compression algorithm known as LZ4 that is better than any other algorithm out there in terms of speed and data compression ratio when it comes to processing web content. This is valid especially when data is uncompressed as LZ4 does that more quickly than it would be to read uncompressed data from a hard disk drive and as a result, websites running on a platform where LZ4 is present will function at a higher speed. We are able to take full advantage of the feature regardless of the fact that it requires quite a lot of CPU processing time because our platform uses a lot of powerful servers working together and we do not make accounts on a single machine like most companies do. There's another benefit of using LZ4 - given that it compresses data very well and does that extremely fast, we can also generate multiple daily backups of all accounts without influencing the performance of the servers and keep them for a whole month. This way, you can always restore any content that you erase by accident.
