In case you use a Virtual Private Server for online and offline programs, you may come across a scenario where they don't perform adequately due to lack of physical memory. This could happen if you try to run a program that requires more RAM than the amount your plan comes with, or in the event that you have too many applications and some of them consume all the memory, leaving no free RAM for the others. Even in the event that you get a powerful plan, this may happen if you include more programs on the server in the future, and since it is possible that you shall need just more physical memory, but not higher Central processing unit speeds or more disk space, we provide a RAM upgrade that you can use without changing your entire plan. Thus, you could pay only for the system resources that you really need and you'll be able to avoid errors on your sites caused by a lack of memory and the inability of the Virtual Private Server to load the programs.
