The more physical memory your Virtual Private Server has, the more applications you will be able to run all at once. Some programs require loads of RAM even if nothing else is running on the hosting server, even though they might not require high Processor speeds or loads of disk space. If your hosting server runs out of memory, it shall stop responding and the sites and the offline programs you host on it will not function effectively, 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, so if you detect that your web server is close to the limit, you may take advantage of this upgrade without upgrading the whole package and paying for resources which you won't use. That way, you'll be able to ensure the proper functioning of your scripts and stop concerning that your website visitors will see errors or won't be able to open your websites at all.
