The more physical memory your Virtual Private Server has, the more apps you shall be able to run simultaneously. Some programs require a lot of RAM even when nothing else is running on the server, even though they may not require high Processor speeds or lots of disk space. If your web server runs out of memory, it shall stop responding and the sites and the offline applications which you host on it will not function adequately, 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 solutions, thus if you discover that your web server is close to the limit, you may take full advantage of this upgrade without upgrading the whole plan and paying for resources which you won't use. In this way, you'll be able to guarantee the proper functioning of your scripts and stop worrying that your website visitors shall see errors or will be unable to open your sites at all.
