The more physical memory your Virtual Private Server has, the more programs you shall be able to run at the same time. Some pieces of software require lots of RAM even when nothing else is running on the hosting server, even though they might not require high CPU speeds or loads of disk space. In case your web server runs out of memory, it shall stop responding and the websites and the offline programs that you host on it will not perform 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 VPS plans, therefore if you notice that your web server is close to the limit, you could take full advantage of this upgrade without upgrading the whole plan and paying for resources that you won't use. In this way, you could guarantee the proper operation of your scripts and stop concerning that your website visitors will see errors or will not be able to open your sites at all.
