Data compression is the reduction of the number of bits that should be stored or transmitted and the process is really important in the internet hosting field because information recorded on hard disk drives is typically compressed so as to take less space. There are different algorithms for compressing information and they provide different efficiency depending on the content. Many of them remove only the redundant bits, so no data will be lost, while others delete unnecessary bits, which results in worse quality once your data is uncompressed. This method employs a lot of processing time, therefore a web hosting server needs to be powerful enough so as to be able to compress and uncompress data in real time. An illustration how binary code can be compressed is by "remembering" that there're five consecutive 1s, for example, rather than storing all five 1s.

Data Compression in Website Hosting

The compression algorithm which we employ on the cloud hosting platform where your new website hosting account shall be created is named LZ4 and it is used by the advanced ZFS file system that powers the platform. The algorithm is far better than the ones other file systems work with because its compression ratio is a lot higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed since this happens quicker than info can be read from a hard disk. Because of this, LZ4 improves the performance of every website hosted on a server that uses this particular algorithm. We take advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to make a number of daily backup copies of the entire content of all accounts and store them for 30 days. Not only do these backups take less space, but their generation won't slow the servers down like it can often happen with various other file systems.

Data Compression in Semi-dedicated Servers

Your semi-dedicated server account shall be created on a cloud platform which is run on the cutting-edge ZFS file system. The aforementioned uses a compression algorithm known as LZ4, that's far better than various 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 much quicker than other algorithms, but it is also faster in uncompressing data than a system is in reading from a hard drive. This is the reason why sites running on a platform which employs LZ4 compression perform faster since the algorithm is most efficient when it processes compressible data i.e. website content. A further advantage of using LZ4 is that the backups of the semi-dedicated accounts that we keep require less space and they are generated quicker, which enables us to store a couple of daily backups of all your files and databases.
