The more physical memory your VPS has, the more applications you will be able to run at the same time. Some apps require a lot of RAM even when nothing else is running on the web server, even though they may not demand high CPU speeds or loads of disk space. In case your hosting server runs out of memory, it will stop responding and the websites and the offline apps you host on it shall not function 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 VPS packages, therefore if you detect that your server is close to the limit, you'll be able to take full advantage of this upgrade without upgrading the whole package and paying for resources that you won't use. In this way, you can ensure the proper performance of your scripts and stop concerning that your site visitors shall see errors or will not be able to open your sites at all.
