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? -- <a href="http://www.tuxedo.org/~esr">Eric S.
