In Bug 1505574, Comment 2 an experiment was performed by disabling unboxed objects. 

In that case, we saw the Speedometer subtest Inferno-TodoMVC/CompletingAllItems lose 23% of its performance. 

We should understand why, and try to understand if we have a strategy to improve that without unboxed objects.
