The more physical memory your Virtual Private Server has, the more apps you'll be able to run concurrently. Some applications require lots of RAM even when 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. In the event your hosting server runs out of memory, it will stop responding and the sites and the offline programs that you host on it won't work properly, as their software components will not load since there won't be any free memory. In this light, we offer a RAM upgrade for our Virtual private server plans, thus if you notice 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 resources which you won't use. That way, you'll be able to guarantee the proper operation of your scripts and stop worrying that your visitors shall see errors or won't be able to open your Internet sites at all.
