Data compression is the lowering of the number of bits that should be stored or transmitted and this particular process is quite important in the internet hosting field as info recorded on hard drives is often compressed to take less space. You'll find different algorithms for compressing information and they have different efficiency depending on the content. A lot of them remove only the redundant bits, so that no data can be lost, while others delete unnecessary bits, which leads to worse quality once the particular data is uncompressed. The process needs a lot of processing time, therefore a hosting server has to be powerful enough so as to be able to compress and uncompress data quickly. An illustration how binary code can be compressed is by "remembering" that there're five consecutive 1s, for example, in contrast to storing all five 1s.
Data Compression in Shared Hosting
The cloud hosting platform where your shared hosting account shall be generated uses the revolutionary ZFS file system. The LZ4 compression method that the latter employs is better in various aspects, and not only does it compress info better than any compression method which some other file systems use, but it is also much faster. The gains will be significant in particular on compressible content like website files. Despite the fact that it may sound illogical, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard disk, so the performance of every website hosted on our servers will be better. The better and faster compression rates also make it possible for us to produce numerous daily backups of the whole content in every single hosting account, so if you delete something by accident, the last back-up copy which we have will not be more than several hours old. This is possible because the backups take much less space and their generation is fast enough, so as to not affect the performance of the servers.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account shall be created on a cloud platform which is run on the leading-edge ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that is far better than alternative algorithms in terms of compression ratio and speed. The gain is apparent especially when data is being uncompressed and not only is LZ4 much quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard disk drive. That's why websites running on a platform which uses LZ4 compression perform better as the algorithm is most efficient when it processes compressible data i.e. web content. One more advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take a lot less space and they're generated quicker, which allows us to store a number of daily backups of your files and databases.
