The more physical memory your Virtual Private Server has, the more programs you will be able to run at the same time. Some pieces of software require a lot of RAM even if nothing else is running on the hosting server, even though they may not require high Central processing unit speeds or a lot of disk space. If your server runs out of memory, it will stop responding and the websites and the offline programs that you host on it will not 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 Virtual private server solutions, therefore if you detect 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 which you won't use. That way, you can guarantee the proper functioning of your scripts and stop stressing that your site visitors will see errors or won't be able to open your websites at all.
