The more physical memory your Virtual Private Server has, the more apps you will be able to run all at once. Some applications require a lot of RAM even when nothing else is running on the web server, even though they may not require high Processor speeds or a lot of disk space. In the event your server runs out of memory, it will stop responding and the sites and the offline apps you host on it will not perform adequately, as their software components won't load since there will not be any free memory. In this light, we offer a RAM upgrade for our Virtual private server plans, therefore if you notice that your server is close to the limit, you'll be able to take full advantage of this upgrade without upgrading the whole plan and paying for system resources that you will not use. In this way, you can guarantee the proper performance of your scripts and stop concerning that your site visitors shall see errors or will be unable to open your Internet sites at all.
