If you use a VPS for online and offline programs, you could come across a scenario where they don't perform properly due to insufficient physical memory. This may take place if you try to run an app that requires additional RAM than the amount your package includes, or in the event that you have too many programs and some of them consume all of the memory, leaving no free RAM for the others. Even in case you get a powerful package, this may happen if you include more applications on the hosting server later on, and since it's possible that you will need simply more physical memory, but not higher Central processing unit speeds or more disk space, we offer a RAM upgrade which you can use without changing your entire plan. In this way, you can pay only for the system resources which you really need and you can avoid errors on your Internet sites caused by a lack of memory and the inability of the Virtual Private Server to load the apps.
