The more physical memory your VPS has, the more programs you shall be able to run concurrently. Some applications require lots of RAM even when nothing else is running on the web server, even though they might not demand high Central processing unit speeds or a lot of disk space. In the event your web server runs out of memory, it'll stop responding and the websites and the offline programs that you host on it will not perform adequately, 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 plans, thus if you notice that your hosting server is close to the limit, you can take advantage of this upgrade without upgrading the whole plan and paying for resources that you will not use. That way, you'll be able to guarantee the proper operation of your scripts and stop concerning that your visitors will see errors or will be unable to open your sites at all.
