Whenever an app is executed on a hosting server, it's 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 situation where your VPS has too little memory to run all the applications and freezes as a result, which means your websites will stop operating correctly and that the visitors will 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 your entire plan. This way, you may pay only for the system resources which you actually need instead of for additional disk space or higher CPU speeds which you won't really use, for example. With the upgrade, you can guarantee the flawless operation of your websites, which also means a better experience for your site visitors.
