The more physical memory your VPS has, the more programs you will be able to run at the same time. Some apps require plenty of RAM even if nothing else is running on the server, even though they may not require high Central processing unit speeds or loads of disk space. If your web server runs out of memory, it shall stop responding and the Internet sites and the offline applications which you host on it will not work properly, as their software components will not load since there will not be any free memory. In this light, we offer a RAM upgrade for our Virtual private server packages, therefore if you detect that your hosting server is close to the limit, you can take full advantage of this upgrade without upgrading the whole package and paying for resources that you won't use. That way, you'll be able to ensure the proper functioning of your scripts and stop worrying that your visitors will see errors or will not be able to open your sites at all.
