Whenever an application is executed on a server, it's loaded into the physical memory. If you run a resource-demanding script, or if you simply add more scripts on your Internet sites and you get a lot of visitors, you might encounter a case where your VPS has not enough memory to run all the apps and freezes because of this, which means that your websites shall stop operating effectively and that the website visitors shall start seeing error messages. To avoid this type of a scenario, you may take advantage of the RAM upgrade that we're offering and increase the amount of physical memory at your disposal without changing the whole plan. This way, you may pay just for the system resources which you actually need instead of for additional disk space or higher Central processing unit speeds that you shall not really use, for example. With the upgrade, you can guarantee the flawless performance of your websites, which also means a better experience for your site visitors.
