The more physical memory your VPS has, the more programs you shall be able to run at the same time. Some programs require lots 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. If your hosting server runs out of memory, it will stop responding and the websites and the offline apps that you host on it shall not function properly, as their software components will not load since there will not be any free memory. In this light, we offer a RAM upgrade for our VPS packages, so 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 system resources that you won't use. This way, you'll be able to guarantee the proper operation of your scripts and stop worrying that your visitors shall see errors or won't be able to open your Internet sites at all.
