Whenever an app is executed on a server, it's loaded into the physical memory. In the event that you run a resource-demanding script, or if you simply add more scripts on your Internet sites and you get loads of visitors, you may encounter a case where your Virtual Private Server has too little memory to run all the programs and freezes for that reason, which means your Internet sites will stop operating properly and that the visitors will start seeing error messages. To avoid this kind of a scenario, you may 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 could pay only for the system resources which you actually need rather than for additional disk space or higher Central processing unit speeds that you will not really use, for example. With the upgrade, you could ensure the flawless performance of your websites, which also means a better experience for your website visitors.
