The more physical memory your Virtual Private Server has, the more programs you will be able to run concurrently. Some apps require lots of RAM even when nothing else is running on the server, even though they may not demand high CPU speeds or loads of disk space. If 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 work effectively, as their software components won't load since there won't be any free memory. In this light, we offer a RAM upgrade for our Virtual private server solutions, therefore if you detect that your server is close to the limit, you may make the most of this upgrade without upgrading the whole package and paying for system resources that you won't use. That way, you'll be able to ensure the proper functioning of your scripts and stop concerning that your site visitors shall see errors or will not be able to open your websites at all.
