The more physical memory your VPS has, the more programs you'll be able to run all at once. Some applications require loads of RAM even when nothing else is running on the web server, even though they may not require high CPU speeds or a lot of disk space. If your server runs out of memory, it shall stop responding and the sites and the offline programs 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, thus if you notice that your web server is close to the limit, you could make the most of this upgrade without upgrading the whole package and paying for resources that you will not use. This way, you could ensure the proper functioning of your scripts and stop concerning that your website visitors shall see errors or will be unable to open your sites at all.
