The more physical memory your Virtual Private Server has, the more apps you will be able to run concurrently. Some applications require loads of RAM even if nothing else is running on the web server, even though they might not require high CPU speeds or loads of disk space. In case your server runs out of memory, it will stop responding and the websites and the offline apps you host on it won't function adequately, 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 Virtual private server plans, therefore if you notice that your web server is close to the limit, you can take full advantage of this upgrade without upgrading the whole plan 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 concerning that your website visitors will see errors or will be unable to open your sites at all.
