The more physical memory your Virtual Private Server has, the more applications you will be able to run all at once. Some pieces of software require lots of RAM even if nothing else is running on the server, even though they might not demand high Central processing unit speeds or loads of disk space. In the event your web server runs out of memory, it will stop responding and the Internet sites and the offline apps that you host on it shall not work effectively, as their software components will not load since there won't be any free memory. In this light, we offer a RAM upgrade for our Virtual private server plans, so if you discover that your server is close to the limit, you could take full advantage of this upgrade without upgrading the whole plan and paying for resources that you will not use. This way, you could guarantee the proper operation of your scripts and stop stressing that your site visitors shall see errors or will be unable to open your Internet sites at all.
