Whenever an app is executed on a web server, it is loaded into the physical memory. If you run a resource-demanding script, or if you just add more scripts on your websites and you get a lot of visitors, you may encounter a situation where your Virtual Private Server has insufficient memory to run all the applications and freezes because of this, which means your sites will stop working correctly and that the website visitors will start seeing error messages. To avoid this kind of a scenario, you may take advantage of the RAM upgrade that we are offering and increase the amount of physical memory for your use without changing the whole plan. That way, you can pay just for the resources which you actually need and not for additional disk space or higher CPU speeds that you will not really use, for instance. With the upgrade, you could ensure the sleek performance of your Internet sites, which also means a better experience for your website visitors.
