The more physical memory your Virtual Private Server 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 server, even though they may not require high CPU speeds or plenty of disk space. If your server runs out of memory, it will stop responding and the Internet sites and the offline applications you host on it won't work properly, as their software components won't load since there won't be any free memory. In this light, we offer a RAM upgrade for our VPS solutions, so if you discover that your server is close to the limit, you can make the most of this upgrade without upgrading the whole package and paying for system resources that you will not use. This way, you'll be able to guarantee the proper operation of your scripts and stop stressing that your site visitors shall see errors or will be unable to open your Internet sites at all.
