The more physical memory your Virtual Private Server has, the more applications you will be able to run simultaneously. Some applications require plenty of RAM even if nothing else is running on the server, even though they might not require high Central processing unit speeds or lots of disk space. In case your hosting server runs out of memory, it shall stop responding and the Internet sites and the offline apps that you host on it will not work properly, 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 VPS packages, therefore if you discover that your hosting server is close to the limit, you can take advantage of this upgrade without upgrading the whole plan and paying for system resources which you won't use. In this way, you'll be able to ensure the proper functioning of your scripts and stop concerning that your website visitors shall see errors or won't be able to open your sites at all.
