The term data compression describes reducing the number of bits of info which needs to be saved or transmitted. You can do this with or without the loss of info, so what will be deleted in the course of the compression shall be either redundant data or unneeded one. When the data is uncompressed later on, in the first case the information and its quality will be the same, whereas in the second case the quality will be worse. You can find various compression algorithms that are more effective for different sort of information. Compressing and uncompressing data usually takes a lot of processing time, which means that the server executing the action must have enough resources to be able to process your info quick enough. A simple example how information can be compressed is to store just how many consecutive positions should have 1 and how many should have 0 inside the binary code as an alternative to storing the actual 1s and 0s.
Data Compression in Cloud Website Hosting
The cloud web hosting platform where your cloud website hosting
account is made employs the innovative ZFS file system. The LZ4 compression method which the latter employs is superior in lots of aspects, and not only does it compress info better than any compression method which other file systems use, but it is also faster. The gains can be significant especially on compressible content such as website files. Although it could sound unreasonable, uncompressing data with LZ4 is faster than reading uncompressed data from a hard disk, so the performance of each and every website hosted on our servers will be upgraded. The better and faster compression rates also allow us to make numerous daily backups of the whole content in each Internet hosting account, so if you delete anything by accident, the last back-up copy which we have will not be more than several hours old. This can be done because the backups take significantly less space and their generation is fast enough, so as to not change the performance of our servers.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be created on a cloud platform which runs using the leading-edge ZFS file system. The aforementioned uses a compression algorithm named LZ4, that is significantly better than alternative algorithms regarding compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 much faster than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. That's why sites running on a platform which uses LZ4 compression perform better since the algorithm is most efficient when it processes compressible data i.e. web content. An additional advantage of using LZ4 is that the backups of the semi-dedicated accounts which we keep need less space and they're generated faster, which enables us to have several daily backups of your files and databases.
