Whenever an application is executed on a web server, it is loaded into the physical memory. If you run a resource-demanding script, or if you simply add more scripts on your websites and you get lots of visitors, you might encounter a case where your Virtual Private Server has insufficient memory to run all the programs and freezes as a result, which means your Internet sites shall stop working adequately and that the site visitors shall 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 at your disposal without changing the whole plan. That way, you could pay only for the system resources which you actually need instead of for additional disk space or higher CPU speeds that you shall not really use, for example. With the upgrade, you'll be able to ensure the flawless performance of your websites, which also means a better experience for your site visitors.
