Whenever a program is executed on a web 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 plenty of visitors, you may encounter a situation where your Virtual Private Server has too little memory to run all the programs and freezes for that reason, which means your sites will stop functioning properly and that the website visitors will start seeing error messages. To avoid this type 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 your entire plan. In this way, you could pay just for the system resources that you actually need instead of for additional disk space or higher Processor speeds which you will not really use, for instance. With the upgrade, you can ensure the faultless operation of your Internet sites, which also means a better experience for your site visitors.
