The more physical memory your Virtual Private Server has, the more programs you shall be able to run concurrently. Some programs require plenty of RAM even when nothing else is running on the server, even though they might not require high CPU speeds or loads of disk space. In the event your server runs out of memory, it shall stop responding and the websites and the offline applications that you host on it will not perform adequately, as their software components shall not load since there won't be any free memory. In this light, we offer a RAM upgrade for our Virtual private server packages, thus if you detect 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 which you won't use. This way, you'll be able to ensure the proper performance of your scripts and stop concerning that your website visitors will see errors or will not be able to open your websites at all.
