The more physical memory your Virtual Private Server has, the more apps you shall be able to run at the same time. Some applications require lots of RAM even when nothing else is running on the server, even though they may not require high Central processing unit speeds or lots of disk space. If your server runs out of memory, it shall stop responding and the sites and the offline apps which you host on it won't perform properly, as their software components won't load since there won't be any free memory. In this light, we offer a RAM upgrade for our Virtual private server packages, therefore if you discover that your server is close to the limit, you'll be able to take full 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 operation of your scripts and stop worrying that your website visitors shall see errors or will not be able to open your sites at all.
