I watched a video on how to reduce minecraft server lag. My server right now is experiencing some lag problems. Its taking a while for chunks to load and breaking blocks and placing blocks in mass number is being weird. This guy on the video made the impression that a ramdisk (on this website) http://memory.dataram.com/products-and-services/software/ramdisk Was basicly free 4gb ram. But is this a good idea? is it adding ram or taking away ram I already have and allocating it to the server. I have 8gb ram and 5gb ram allocated to my server. When I run Chrome, files, my server, and minecraft, the Performance in the task manager goes up to about 7.80GB. Is the only answer to buy more ram, or can I do this ramdisk thing and get 9GB ram to my server?
