The more physical memory your VPS has, the more programs you'll be able to run concurrently. Some programs require plenty of RAM even when nothing else is running on the hosting server, even though they may not demand high Central processing unit speeds or loads of disk space. If your server runs out of memory, it shall stop responding and the Internet sites and the offline programs you host on it will not function 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, thus if you notice that your server is close to the limit, you may take full advantage of this upgrade without upgrading the whole plan and paying for system resources which you won't use. This way, you can ensure the proper performance of your scripts and stop stressing that your site visitors will see errors or will be unable to open your websites at all.
