|  | # JIT (5) - Optimal JIT? |

- simple coherence, difficult conclusion: execution time depends on optimization time

- there is a different "break even" number of calls for each JITed method

- number of calls cannot be predicted in advance

- adaptive JIT compilation (intrp/JIT) adds additional overhead

- adaptive JIT optimization (global reg, peephole) depending on verifier output seems to be better
