The more physical memory your Virtual Private Server has, the more apps you shall be able to run concurrently. Some programs require plenty of RAM even when nothing else is running on the web server, even though they may not require high Processor speeds or plenty of disk space. If your web server runs out of memory, it shall stop responding and the Internet sites and the offline apps which you host on it will not function properly, 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 notice that your machine is close to the limit, you could take advantage of this upgrade without upgrading the whole plan and paying for resources that you won't use. That way, you'll be able to ensure the proper performance of your scripts and stop stressing that your website visitors shall see errors or won't be able to open your Internet sites at all.
