The more physical memory your Virtual Private Server has, the more programs you'll be able to run concurrently. Some applications 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 lots of disk space. In case your web server runs out of memory, it will stop responding and the sites and the offline programs that you host on it will not work properly, as their software components won't load since there won't be any free memory. In this light, we offer a RAM upgrade for our Virtual private server plans, therefore if you detect that your server is close to the limit, you can take advantage of this upgrade without upgrading the whole plan and paying for system resources that you won't use. This way, you'll be able to ensure the proper functioning of your scripts and stop worrying that your website visitors will see errors or will be unable to open your sites at all.
