The more physical memory your Virtual Private Server has, the more apps you shall be able to run simultaneously. Some programs require plenty of RAM even when nothing else is running on the web server, even though they may not require high Processor speeds or loads of disk space. In the event your web server runs out of memory, it will stop responding and the websites and the offline programs which you host on it won't perform 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 solutions, thus if you discover that your server is close to the limit, you'll be able to take advantage of this upgrade without upgrading the whole package and paying for system resources which you won't use. That way, you could guarantee the proper operation of your scripts and stop concerning that your site visitors will see errors or will be unable to open your websites at all.
