The more physical memory your VPS has, the more apps you'll be able to run at the same time. Some programs require lots of RAM even when nothing else is running on the web server, even though they might not demand high Central processing unit speeds or plenty of disk space. If your hosting server runs out of memory, it'll stop responding and the sites and the offline apps that you host on it won't work effectively, 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 notice that your web server is close to the limit, you'll be able to make the most 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 functioning of your scripts and stop concerning that your website visitors shall see errors or won't be able to open your Internet sites at all.
