The more physical memory your Virtual Private Server has, the more apps you shall be able to run simultaneously. Some pieces of software require loads of RAM even when nothing else is running on the server, even though they may not require high CPU speeds or loads of disk space. In case your web server runs out of memory, it will stop responding and the websites and the offline apps which you host on it shall not perform adequately, as their software components shall not load since there will not be any free memory. In this light, we offer a RAM upgrade for our VPS packages, therefore if you notice that your machine is close to the limit, you may take full advantage of this upgrade without upgrading the whole plan and paying for system resources that you will not use. This way, you can ensure the proper operation of your scripts and stop worrying that your site visitors will see errors or won't be able to open your sites at all.
