The more physical memory your Virtual Private Server has, the more programs you shall be able to run simultaneously. Some programs require loads of RAM even if nothing else is running on the hosting server, even though they might not demand high Processor speeds or a lot of disk space. In case your server runs out of memory, it will stop responding and the sites and the offline apps that you host on it will not work 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, thus if you detect that your server is close to the limit, you'll be able to make the most of this upgrade without upgrading the whole plan and paying for system resources which you won't use. This way, you can guarantee the proper functioning of your scripts and stop worrying that your visitors will see errors or will not be able to open your websites at all.
