Whenever a program is executed on a hosting server, it is loaded into the physical memory. In case you run a resource-demanding script, or if you simply add more scripts on your websites and you get loads of visitors, you may encounter a case where your Virtual Private Server has not enough memory to run all the apps and freezes because of this, which means your sites shall stop working effectively and that the website visitors shall start seeing error messages. To avoid such a scenario, you'll be able to take advantage of the RAM upgrade that we're offering and increase the amount of physical memory available without changing the whole plan. This way, you'll be able to pay just for the system resources you actually need instead of for additional disk space or higher Central processing unit speeds that you won't really use, for instance. With the upgrade, you can ensure the faultless operation of your websites, which also means a better experience for your website visitors.
