The more physical memory your Virtual Private Server has, the more applications you'll be able to run simultaneously. Some pieces of software require lots of RAM even when nothing else is running on the web server, even though they might not demand high CPU speeds or a lot of disk space. In the event your web server runs out of memory, it will stop responding and the websites and the offline apps that you host on it won't perform adequately, as their software components shall not load since there will not be any free memory. In this light, we offer a RAM upgrade for our Virtual private server plans, thus if you discover that your server is close to the limit, you can take advantage of this upgrade without upgrading the whole plan and paying for resources which you won't use. In this way, you can guarantee the proper performance of your scripts and stop worrying that your site visitors will see errors or won't be able to open your websites at all.
