Which programming languages are fastest?

No. Which programming language implementations have the fastest benchmark programs?

This chart shows one comparison - program Time-used (Elapsed secs) ÷ fastest program Time-used. Each chart box shows the middle 50% program times ÷ fastest program times for 10 tiny tasks. Each horizontal black bar shows ↓ the median program time ÷ fastest program time for 10 tiny tasks.
