The more physical memory your VPS has, the more apps you'll be able to run at the same time. Some programs require a lot of RAM even if nothing else is running on the web server, even though they may not demand high Central processing unit speeds or plenty of disk space. In case your web server runs out of memory, it will stop responding and the sites and the offline programs you host on it will not perform 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 solutions, therefore if you notice that your machine is close to the limit, you could make the most of this upgrade without upgrading the whole package and paying for resources that you will not use. That way, you can ensure the proper performance of your scripts and stop concerning that your site visitors will see errors or will be unable to open your websites at all.
