Data compression is the compacting of info by reducing the number of bits that are stored or transmitted. In this way, the compressed info requires substantially less disk space than the original one, so more content can be stored on identical amount of space. There're various compression algorithms that function in different ways and with several of them just the redundant bits are erased, which means that once the info is uncompressed, there is no loss of quality. Others erase unneeded bits, but uncompressing the data later will lead to lower quality in comparison with the original. Compressing and uncompressing content requires a huge amount of system resources, and in particular CPU processing time, so each and every Internet hosting platform that uses compression in real time must have ample power to support this attribute. An example how information can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" the number of sequential 1s or 0s there should be instead of saving the actual code.
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 called LZ4 and it is applied by the advanced ZFS file system which powers the platform. The algorithm is more advanced than the ones other file systems use because its compression ratio is higher and it processes data a lot faster. The speed is most noticeable when content is being uncompressed as this happens faster than info can be read from a hdd. Consequently, LZ4 improves the performance of each website stored on a server that uses this particular algorithm. We use LZ4 in one more way - its speed and compression ratio make it possible for us to produce a number of daily backups of the full content of all accounts and store them for thirty days. Not only do the backups take less space, but in addition their generation doesn't slow the servers down like it often happens with various other file systems.
Data Compression in Semi-dedicated Servers
The ZFS file system which runs on the cloud platform where your semi-dedicated server account will be created uses a powerful compression algorithm called LZ4. It is among the best algorithms out there and definitely the most efficient one when it comes to compressing and uncompressing web content, as its ratio is very high and it'll uncompress data quicker than the same data can be read from a hard disk drive if it were uncompressed. This way, using LZ4 will accelerate any kind of website that runs on a platform where the algorithm is enabled. The high performance requires a lot of CPU processing time, which is provided by the numerous clusters working together as a part of our platform. What's more, LZ4 makes it possible for us to generate several backup copies of your content every day and save them for a month as they will take much less space than regular backups and will be generated considerably quicker without loading the servers.
