Well by frame 300 you have 60,000 rigidbodies, so yes...that will be slow. But I'm not sure why it's taking 4 hours on your machine. After frame 300, on my machine, when the sim is heaviest with all 60k rigidbodies...it takes about 2.5 seconds per frame to simulate (and I have the same CPU that you have)...so frame 300-600 would take about 10-15 minutes to finish simulating. That's pretty reasonable, given the complexity of the scene.
