There’s a significant pause before a first Debug.Log is executed after waiting for threads to complete
Repro steps:
1. Open user attached project
2. Enter Play Mode and press either one of the buttons in the Game View
3. Observe the messages in the Game View or in the Console
Notice that the time taken for the first Debug.Log message is significantly higher than for the second one
4. Repeat steps 2-3
Notice that now the time for both Debug.Log messages is similar
5. Exit Play Mode, open the LogAfterThreads script and uncomment the Debug.Log statement in the Start method
6. Repeat steps 2-3
Now the pause before the first Debug.Log call doesn’t occur

This is not a bug. If you look at the profiler, you'll see that the increased time is spent in Mono JIT.
