Yeah figured that out. I let it make a world, stopped it, altered the settings, copied over a singleplayer world and the server seems to be running fine now.Easiest way is start a world let it load all the properties and stuff, stop the server, delete the world it made and change properties as you see fit
Just got one problem. I cannot see the server in the client. Do I need to do something special for it to work when on the same PC?

FPS spikes caused by the memory dumps seems to be almost completely gone.
