Data compression is the compacting of info by lowering the number of bits that are stored or transmitted. This way, the compressed data will take much less disk space than the initial one, so extra content might be stored on identical amount of space. You will find different compression algorithms that function in different ways and with several of them only the redundant bits are deleted, so once the info is uncompressed, there is no decrease in quality. Others remove unnecessary bits, but uncompressing the data afterwards will result in reduced quality compared to the original. Compressing and uncompressing content requires a large amount of system resources, especially CPU processing time, therefore every web hosting platform that employs compression in real time should have enough power to support this attribute. An example how info can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" how many sequential 1s or 0s there should be instead of storing the entire code.
Data Compression in Shared Website Hosting
The compression algorithm that we work with on the cloud internet hosting platform where your new shared website hosting
account shall be created is known as LZ4 and it's applied by the leading-edge ZFS file system which powers the platform. The algorithm is greater than the ones other file systems employ as its compression ratio is higher and it processes data significantly faster. The speed is most noticeable when content is being uncompressed as this happens faster than data can be read from a hard drive. For that reason, LZ4 improves the performance of each website located on a server that uses this algorithm. We take full advantage of LZ4 in one more way - its speed and compression ratio make it possible for us to generate a couple of daily backups of the full content of all accounts and keep them for 30 days. Not only do the backup copies take less space, but in addition their generation doesn't slow the servers down like it often happens with some other file systems.
Data Compression in Semi-dedicated Hosting
The ZFS file system which runs on the cloud platform where your semi-dedicated hosting
account will be created uses a powerful compression algorithm called LZ4. It is among the best algorithms out there and positively the best one when it comes to compressing and uncompressing website content, as its ratio is very high and it'll uncompress data at a faster rate than the same data can be read from a hard disk drive if it were uncompressed. Thus, using LZ4 will boost any kind of website that runs on a platform where the algorithm is enabled. The high performance requires plenty of CPU processing time, that's provided by the great number of clusters working together as a part of our platform. Furthermore, LZ4 allows us to generate several backup copies of your content every day and save them for one month as they will take a reduced amount of space than standard backups and will be created much quicker without loading the servers.
