The more physical memory your VPS has, the more programs you shall be able to run at the same time. Some pieces of software require loads of RAM even if nothing else is running on the web server, even though they may not require high Processor speeds or lots of disk space. In case your server runs out of memory, it shall stop responding and the Internet sites and the offline applications you host on it won't function adequately, 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 packages, therefore if you discover that your web server is close to the limit, you'll be able to take full advantage of this upgrade without upgrading the whole plan and paying for system resources which you won't use. That way, you can guarantee the proper functioning of your scripts and stop worrying that your website visitors shall see errors or will not be able to open your websites at all.
