The more physical memory your VPS has, the more applications you will be able to run at the same time. Some applications require loads of RAM even when nothing else is running on the web server, even though they may not demand high CPU speeds or plenty of disk space. If your web server runs out of memory, it'll stop responding and the sites and the offline programs which you host on it will not 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 solutions, so if you discover that your web server is close to the limit, you'll be able to take advantage of this upgrade without upgrading the whole package and paying for resources which you won't use. This way, you could ensure the proper performance of your scripts and stop worrying that your visitors will see errors or will not be able to open your Internet sites at all.
