Whenever an application is executed on a web server, it is loaded into the physical memory. In the event that you run a resource-demanding script, or if you simply add more scripts on your websites and you get loads of visitors, you might encounter a case where your Virtual Private Server has too little memory to run all the programs and freezes because of this, which means your websites shall stop functioning effectively and that the site visitors will start seeing error messages. To avoid this type 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 entire plan. That way, you can pay just for the resources you actually need instead of for additional disk space or higher CPU speeds that you won't really use, for example. With the upgrade, you can guarantee the faultless performance of your sites, which also means a better experience for your website visitors.
