The more physical memory your Virtual Private Server has, the more applications you'll be able to run all at once. Some programs require lots of RAM even when nothing else is running on the web server, even though they might not demand high Central processing unit speeds or lots of disk space. In case your server runs out of memory, it will stop responding and the sites and the offline apps which you host on it shall not work effectively, as their software components won't load since there will not be any free memory. In this light, we offer a RAM upgrade for our VPS solutions, therefore if you detect that your server is close to the limit, you can take full advantage of this upgrade without upgrading the whole package and paying for resources that you won't use. That way, you can guarantee the proper performance of your scripts and stop stressing that your visitors shall see errors or won't be able to open your websites at all.
