Data compression is the compacting of information by decreasing the number of bits that are stored or transmitted. Consequently, the compressed information requires substantially less disk space than the original one, so much more content can be stored using the same amount of space. There're different compression algorithms that work in different ways and with several of them just the redundant bits are deleted, so once the information is uncompressed, there is no loss of quality. Others remove unneeded bits, but uncompressing the data later on will result in reduced quality in comparison with the original. Compressing and uncompressing content takes a huge amount of system resources, especially CPU processing time, so each and every hosting platform which employs compression in real time should have adequate power to support that feature. An example how data can be compressed is to substitute a binary code such as 111111 with 6x1 i.e. "remembering" what number of sequential 1s or 0s there should be instead of storing the actual code.

Data Compression in Shared Hosting

The compression algorithm employed by the ZFS file system which runs on our cloud web hosting platform is known as LZ4. It can boost the performance of any Internet site hosted in a shared hosting account on our end as not only does it compress data significantly better than algorithms used by various 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 lot of CPU processing time, which is not a problem for our platform due to the fact that it uses clusters of powerful servers working together. One more advantage of LZ4 is that it allows us to generate backup copies more quickly and on reduced disk space, so we will have a couple of daily backups of your files and databases and their generation won't affect the performance of the servers. In this way, we can always restore all content that you could have deleted by accident.

Data Compression in Semi-dedicated Servers

The semi-dedicated server plans which we supply are created on a powerful cloud platform that runs on the ZFS file system. ZFS employs a compression algorithm called LZ4 that is greater than any other algorithm available on the market in terms of speed and compression ratio when it comes to processing web content. This is valid especially when data is uncompressed since LZ4 does that much faster than it would be to read uncompressed data from a hard drive and because of this, Internet sites running on a platform where LZ4 is present will work quicker. We're able to take advantage of this feature despite of the fact that it requires quite a considerable amount of CPU processing time because our platform uses a lot of powerful servers working together and we don't make accounts on just a single machine like the vast majority of companies do. There is another reward of using LZ4 - given that it compresses data rather well and does that very fast, we can also make multiple daily backups of all accounts without affecting the performance of the servers and keep them for a month. By doing this, you'll always be able to bring back any content that you delete by mistake.
