Whenever a program is executed on a hosting server, it's loaded into the physical memory. In case you run a resource-demanding script, or if you simply add more scripts on your sites and you get a lot of visitors, you may encounter a situation where your VPS has insufficient memory to run all the applications and freezes as a result, which means your sites shall stop functioning properly and that the website visitors shall start seeing error messages. To avoid this sort of a scenario, you can take advantage of the RAM upgrade that we're offering and increase the amount of physical memory you can use without changing your entire plan. This way, you may pay just for the system resources which you actually need and not for additional disk space or higher Processor speeds which you will not really use, for example. With the upgrade, you could ensure the sleek functioning of your Internet sites, which also means a better experience for your visitors.
