Some thoughts:
1. That looks as close to a Poisson distribution as makes no difference.
I wonder what that means?
2. Microtuning in the implementations of the top 3 opcodes looks indicated,
as they seem to constitute more than 50% of all calls.
3. On the other hand, what do you get when you weight these by average
time per opcode?
