Baking Way Slower Than Playback?

[user_deleted]

Using rigid bodies and suddenly I am finding that baking is taking 100 times longer than just playing the sim.
playback is almost realtime,
baking is one frame every 5 seconds.
Am I doing something wrong?

Are you oversampling. Also the playback may allready be cached. Plus baking is mostly up to the speed of your hard drive.

Ok found the issue, posting FYI.
I had baked my simulation in stages (simulate the "big" stuff, bake into passive Rigidbodies, then simulate the small stuff)
and under my "big" RB's I had parented new shapes and turned those into passive RBs.
played fine, but baking was freezing.
