Here you can have a look at our tps-graphs for the past 24-hours. It should pretty much flatline near the 20tps border. World saving may cause a temporary spike.
Let's play a game: Imagine 100+ different beans (in the colors of rainbow, all kinds of shapes and sizes) knit together with a string. Then attach 200 hooks with more string to the mesh of beans. Throw a fishing net over the contraption. Now turn off the lights in the small closet that you've done this in. An angry giant has at this point lifted the closet high in the air and the closet shakes rather violently. Your task is now to keep the beans touching other beans and to keep the fishnet, hooks and strings from becoming an unmanageable mess. Congratulations, you're now an admin :)
