The more physical memory your Virtual Private Server has, the more programs you will be able to run simultaneously. Some pieces of software require lots of RAM even when nothing else is running on the hosting server, even though they might not demand high CPU speeds or plenty 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 will not perform 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 VPS plans, therefore if you notice that your web 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 resources that you will not use. In this way, you could guarantee the proper operation of your scripts and stop worrying that your website visitors will see errors or will not be able to open your sites at all.
