The more physical memory your VPS has, the more applications you will be able to run all at once. Some applications require loads of RAM even when nothing else is running on the web server, even though they might not require high Processor speeds or loads of disk space. If your web server runs out of memory, it shall stop responding and the Internet sites and the offline programs you host on it shall not work adequately, 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 VPS packages, therefore if you discover that your web server is close to the limit, you may make the most of this upgrade without upgrading the whole plan and paying for system resources that you will not use. In this way, you'll be able to guarantee the proper functioning of your scripts and stop stressing that your visitors will see errors or will not be able to open your websites at all.
