If you use a VPS for online and offline programs, you might come across a case where they do not perform adequately as a result of insufficient physical memory. This can happen if you try to run a program which requires additional RAM than the amount your package deal provides, or if you have too many programs and some of them consume all the memory, leaving no free RAM for the others. Even when you get a powerful package, this may happen if you add more applications on the server in the future, and since it's possible that you'll need only more physical memory, but not higher CPU speeds or more disk space, our company offers a RAM upgrade which you can use without changing your whole plan. In this way, you can pay only for the system resources that you really need and you can avoid errors on your Internet sites caused by insufficient memory and the inability of the Virtual Private Server to load the apps.
