The more physical memory your Virtual Private Server has, the more programs you shall be able to run concurrently. Some apps require a lot of RAM even when nothing else is running on the web server, even though they may not require high Central processing unit speeds or loads of disk space. If your web server runs out of memory, it will stop responding and the Internet sites and the offline apps that you host on it won't work properly, 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 VPS solutions, therefore if you detect that your web server is close to the limit, you'll be able to make the most of this upgrade without upgrading the whole package and paying for system resources that you won't use. That way, you could guarantee the proper performance of your scripts and stop concerning that your website visitors shall see errors or will not be able to open your sites at all.
