Learn exactly what Data Compression is and find out how it may affect your websites and the experience of your website visitors.
Data compression is the compacting of data by decreasing the number of bits which are stored or transmitted. Because of this, the compressed info will need much less disk space than the initial one, so additional content might be stored using the same amount of space. You'll find various compression algorithms which work in different ways and with several of them only the redundant bits are removed, which means that once the data is uncompressed, there is no decrease in quality. Others erase excessive bits, but uncompressing the data following that will result in lower quality compared to the original. Compressing and uncompressing content consumes a significant amount of system resources, and in particular CPU processing time, therefore every hosting platform that uses compression in real time must have sufficient power to support this feature. An example how information can be compressed is to replace a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of keeping the entire code.
Data Compression in Cloud Website Hosting
The compression algorithm employed by the ZFS file system which runs on our cloud internet hosting platform is called LZ4. It can boost the performance of any website hosted in a cloud website hosting
account on our end as not only does it compress data more efficiently than algorithms employed by other file systems, but it also uncompresses data at speeds which are higher than the hard drive reading speeds. This can be done by using a great deal of CPU processing time, which is not a problem for our platform owing to the fact that it uses clusters of powerful servers working together. An additional advantage of LZ4 is that it allows us to make backups much more rapidly and on reduced disk space, so we can have multiple daily backups of your files and databases and their generation will not influence the performance of the servers. That way, we can always restore the content that you may have deleted by accident.
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's one of the best algorithms out there and positively the most efficient one when it comes to compressing and uncompressing website content, as its ratio is very high and it'll uncompress data faster 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 present. 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 enables us to generate several backups of your content every day and save them for one month as they will take much less space than typical backups and will be generated considerably faster without loading the servers.
