The more physical memory your VPS has, the more apps you will be able to run at the same time. Some pieces of software require a lot of RAM even if nothing else is running on the web server, even though they might not require high Central processing unit speeds or lots of disk space. If your server runs out of memory, it will stop responding and the Internet sites and the offline applications that you host on it shall not work adequately, as their software components won't load since there won't be any free memory. In this light, we offer a RAM upgrade for our Virtual private server packages, therefore if you notice that your server is close to the limit, you can take full advantage of this upgrade without upgrading the whole package and paying for resources that you won't use. That way, you can ensure the proper performance of your scripts and stop concerning that your site visitors shall see errors or won't be able to open your Internet sites at all.
