The more physical memory your VPS has, the more apps you shall be able to run simultaneously. Some pieces of software require lots of RAM even if nothing else is running on the hosting server, even though they might not require high Central processing unit speeds or loads of disk space. If your web server runs out of memory, it will stop responding and the sites and the offline apps you host on it won't work properly, as their software components will not load since there will not be any free memory. In this light, we offer a RAM upgrade for our Virtual private server packages, therefore if you notice that your server is close to the limit, you can make the most of this upgrade without upgrading the whole plan and paying for resources that you won't use. That way, you'll be able to ensure the proper operation of your scripts and stop stressing that your site visitors will see errors or will not be able to open your sites at all.
