The more physical memory your Virtual Private Server has, the more apps you will be able to run all at once. Some apps require lots of RAM even if nothing else is running on the hosting server, even though they might not demand high Processor speeds or loads of disk space. In the event your server runs out of memory, it shall stop responding and the Internet sites and the offline programs that you host on it won't function adequately, 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 solutions, therefore if you notice that your machine is close to the limit, you'll be able to take advantage of this upgrade without upgrading the whole package and paying for system resources which you won't use. This way, you can ensure the proper performance of your scripts and stop stressing that your site visitors will see errors or won't be able to open your websites at all.
