The more physical memory your Virtual Private Server has, the more programs you will be able to run simultaneously. Some applications require plenty of RAM even when nothing else is running on the hosting server, even though they may not demand high CPU speeds or loads of disk space. In case your web server runs out of memory, it'll stop responding and the Internet sites and the offline programs which you host on it will not perform effectively, as their software components will not 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 notice that your hosting server is close to the limit, you'll be able to take full advantage of this upgrade without upgrading the whole plan and paying for system resources which you won't use. That way, you could ensure the proper performance of your scripts and stop stressing that your website visitors will see errors or will not be able to open your websites at all.
