Whenever an app is executed on a hosting 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 may encounter a situation where your Virtual Private Server has not enough memory to run all the applications and freezes for that reason, which means your sites shall stop operating adequately and that the site visitors shall start seeing error messages. To avoid this sort of a scenario, you can take advantage of the RAM upgrade that we are offering and increase the amount of physical memory you can use without changing the whole plan. This way, you can pay only for the system resources you actually need and not for additional disk space or higher CPU speeds that you will not really use, for instance. With the upgrade, you can guarantee the faultless operation of your sites, which also means a better experience for your website visitors.
