Whenever an application is executed on a web server, it's loaded into the physical memory. In case you run a resource-demanding script, or if you simply add more scripts on your Internet sites and you get plenty of visitors, you may encounter a scenario where your Virtual Private Server has too little memory to run all the apps and freezes as a result, which means that your sites shall stop functioning effectively and that the visitors shall start seeing error messages. To avoid such a scenario, you may take advantage of the RAM upgrade that we're offering and increase the amount of physical memory you can use without changing the entire plan. That way, you could pay just for the resources that you actually need instead of for additional disk space or higher CPU speeds that you shall not really use, for instance. With the upgrade, you can ensure the faultless functioning of your Internet sites, which also means a better experience for your visitors.
