The term data compression means reducing the number of bits of info that needs to be saved or transmitted. You can do this with or without losing data, which means that what will be removed in the course of the compression can be either redundant data or unnecessary one. When the data is uncompressed subsequently, in the first case the content and the quality will be identical, whereas in the second case the quality will be worse. There are different compression algorithms which are better for different sort of data. Compressing and uncompressing data generally takes plenty of processing time, so the server performing the action needs to have plenty of resources to be able to process your info fast enough. A simple example how information can be compressed is to store just how many sequential positions should have 1 and just how many should have 0 within the binary code as an alternative to storing the actual 1s and 0s.
Data Compression in Website Hosting
The cloud internet hosting platform where your website hosting account shall be generated employs the reliable ZFS file system. The LZ4 compression method which the aforementioned employs is superior in many aspects, and not only does it compress info better than any compression method that a number of other file systems use, but it is also much quicker. The gains may be significant particularly on compressible content which includes website files. While it could sound unreasonable, uncompressing data with LZ4 is quicker than reading uncompressed data from a hard drive, so the performance of each website hosted on our servers will be boosted. The better and faster compression rates also allow us to produce a number of daily backups of the whole content in each hosting account, so should you delete something by mistake, the last back-up copy that we have will not be more than a couple of hours old. This is possible as the backups take a lot less space and their generation is fast enough, so as to not affect the performance of the servers.
Data Compression in Semi-dedicated Hosting
The ZFS file system that runs on the cloud platform where your semi-dedicated hosting account will be created uses a powerful compression algorithm called LZ4. It's among the best algorithms out there and certainly the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it can uncompress data quicker than the same data can be read from a hard drive if it were uncompressed. This way, using LZ4 will quicken any site that runs on a platform where this algorithm is enabled. The high performance requires lots of CPU processing time, that is provided by the large number of clusters working together as a part of our platform. In addition to that, 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 a smaller amount of space than typical backups and will be generated much more quickly without loading the servers.
