The more physical memory your Virtual Private Server has, the more apps you shall be able to run at the same time. Some programs require plenty of RAM even if nothing else is running on the web server, even though they may not demand high Central processing unit speeds or loads of disk space. In case your server runs out of memory, it will stop responding and the sites and the offline applications that you host on it will not function 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 VPS solutions, thus if you detect that your server is close to the limit, you'll be able to take full advantage of this upgrade without upgrading the whole package and paying for resources that you won't use. This way, you'll be able to guarantee the proper performance of your scripts and stop stressing that your visitors will see errors or won't be able to open your Internet sites at all.
