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 Internet sites and you get plenty of visitors, you might encounter a scenario where your VPS has not enough memory to run all the programs and freezes as a result, which means that your websites will stop functioning adequately and that the site visitors shall start seeing error messages. To avoid this kind of a scenario, you'll be able to take advantage of the RAM upgrade that we're offering and increase the amount of physical memory you can use without changing the whole plan. In this way, you could pay only for the 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 could guarantee the sleek operation of your Internet sites, which also means a better experience for your visitors.
