Data compression is the lowering of the number of bits that have to be saved or transmitted and this process is rather important in the web hosting field because info located on hard drives is typically compressed to take less space. You'll find many different algorithms for compressing information and they have different efficiency depending on the content. A lot of them remove only the redundant bits, so no data can be lost, while others erase unnecessary bits, which leads to worse quality once the data is uncompressed. This process uses plenty of processing time, so a web hosting server should be powerful enough so as to be able to compress and uncompress data instantly. An illustration how binary code could be compressed is by "remembering" that there're five sequential 1s, for example, as an alternative to storing all five 1s.

Data Compression in Shared Hosting

The compression algorithm that we use on the cloud web hosting platform where your new shared hosting account will be created is known as LZ4 and it is applied by the exceptional ZFS file system that powers the platform. The algorithm is far better than the ones other file systems employ as its compression ratio is 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 data can be read from a hard drive. Therefore, LZ4 improves the performance of any site stored on a server that uses the algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to generate a number of daily backup copies of the whole content of all accounts and keep them for a month. Not only do our backups take less space, but also their generation doesn't slow the servers down like it can often happen with various other file systems.

Data Compression in Semi-dedicated Servers

If you host your sites in a semi-dedicated server account from our firm, you can experience the advantages of LZ4 - the powerful compression algorithm used by the ZFS file system that is behind our advanced cloud web hosting platform. What differentiates LZ4 from all of the other algorithms out there is that it has a better compression ratio and it is considerably faster, in particular with regard to uncompressing website content. It does that even quicker than uncompressed data can be read from a hard disk drive, so your sites will perform better. The higher speed comes at the expense of using lots of CPU processing time, that is not a problem for our platform as it consists of a large number of clusters working together. Besides the improved performance, you'll also have multiple daily backup copies at your disposal, so you can restore any deleted content with a few clicks. The backup copies are available for an entire month and we can afford to store them as they need a lot less space compared to conventional backups.
