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