Data compression is the decrease of the number of bits which need to be saved or transmitted and this process is quite important in the web hosting field due to the fact that info kept on hard disk drives is typically compressed so as to take less space. There're many different algorithms for compressing information and they have different effectiveness based upon the content. Some of them remove just the redundant bits, so no data can be lost, while others erase unnecessary bits, which results in worse quality once the data is uncompressed. This process employs a lot of processing time, so a web hosting server has to be powerful enough to be able to compress and uncompress data instantly. An instance how binary code could be compressed is by "remembering" that there are five consecutive 1s, for example, rather than storing all five 1s.

Data Compression in Shared Website Hosting

The compression algorithm that we employ on the cloud web hosting platform where your new shared website hosting account shall be created is called LZ4 and it's used by the advanced ZFS file system that powers the platform. The algorithm is far better than the ones other file systems employ since its compression ratio is a lot higher and it processes data considerably faster. The speed is most noticeable when content is being uncompressed as this happens at a faster rate than information can be read from a hard disk. Therefore, LZ4 improves the performance of each Internet site located on a server that uses this algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio allow us to generate multiple daily backups of the whole content of all accounts and store them for a month. Not only do our backup copies take less space, but their generation doesn't slow the servers down like it can often happen with alternative file systems.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account will be created on a cloud platform which is run on the innovative ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that's far better than all the other algorithms in terms of compression ratio and speed. The gain is visible particularly when data is being uncompressed and not only is LZ4 faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a HDD. That's why websites running on a platform which uses LZ4 compression perform faster as the algorithm is most efficient when it processes compressible data i.e. site content. An additional advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep take significantly less space and are generated faster, which allows us to have a number of daily backups of all your files and databases.
