Data compression is the decrease of the number of bits that have to be saved or transmitted and the process is quite important in the internet hosting field since info stored on hard disk drives is typically compressed so as to take less space. You'll find many different algorithms for compressing info and they provide different efficiency based on the content. Some of them remove only the redundant bits, so that no data can be lost, while others erase unneeded bits, which results in worse quality when the data is uncompressed. The method employs plenty of processing time, which means that an internet hosting server needs to be powerful enough in order to be able to compress and uncompress data instantly. An illustration how binary code could be compressed is by "remembering" that there are five sequential 1s, for example, as an alternative to storing all five 1s.

Data Compression in Shared Hosting

The ZFS file system that is run on our cloud web hosting platform employs a compression algorithm identified as LZ4. The aforementioned is a lot faster and better than every other algorithm available on the market, particularly for compressing and uncompressing non-binary data i.e. web content. LZ4 even uncompresses data quicker than it is read from a hard disk, which improves the overall performance of Internet sites hosted on ZFS-based platforms. Since the algorithm compresses data really well and it does that very fast, we can generate several backups of all the content kept in the shared hosting accounts on our servers every day. Both your content and its backups will take less space and since both ZFS and LZ4 work very quickly, the backup generation will not influence the performance of the web servers where your content will be stored.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform that is run on the advanced ZFS file system. The aforementioned uses a compression algorithm called LZ4, which is a lot better than various other algorithms regarding compression ratio and speed. The gain is significant especially when data is being uncompressed and not only is LZ4 a lot faster than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard drive. That's why sites running on a platform that employs LZ4 compression perform better as the algorithm is most effective when it processes compressible data i.e. site content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep need much less space and they're generated a lot faster, which allows us to keep multiple daily backups of all your files and databases.
