Data compression is the decrease of the number of bits that have to be stored or transmitted and this particular process is really important in the internet hosting field since data recorded on hard disks is often compressed so as to take less space. You'll find different algorithms for compressing info and they have different efficiency based on the content. A number of them remove only the redundant bits, so that no data can be lost, while others delete unneeded bits, which results in worse quality when your data is uncompressed. The method consumes a lot of processing time, therefore an internet hosting server needs to be powerful enough to be able to compress and uncompress data instantly. An example how binary code can be compressed is by "remembering" that there are five consecutive 1s, for example, as an alternative to storing all five 1s.
Data Compression in Hosting
The compression algorithm that we employ on the cloud web hosting platform where your new hosting account will be created is known as LZ4 and it's applied by the state-of-the-art ZFS file system which powers the system. The algorithm is much better than the ones other file systems work with as its compression ratio is a lot higher and it processes data significantly 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. Because of this, LZ4 improves the performance of any site hosted on a server which uses the algorithm. We use LZ4 in one more way - its speed and compression ratio let us produce multiple daily backups of the entire content of all accounts and keep them for a month. Not only do these backups take less space, but also their generation does not slow the servers down like it can often happen with many other file systems.
Data Compression in Semi-dedicated Hosting
Your semi-dedicated hosting account will be created on a cloud platform that is run on the leading-edge ZFS file system. The latter uses a compression algorithm called LZ4, that's much better than all the other algorithms when it comes to compression ratio and speed. The gain is visible especially when data is being uncompressed and not only is LZ4 quicker than other algorithms, but it is also quicker in uncompressing data than a system is in reading from a hard drive. That is why Internet sites running on a platform that uses LZ4 compression perform better since the algorithm is most efficient when it processes compressible data i.e. website content. Another advantage of using LZ4 is that the backup copies of the semi-dedicated accounts that we keep require significantly less space and are generated a lot faster, which allows us to have several daily backups of your files and databases.
