Compare the performance of ≈30 programming languages
using ≈12 flawed benchmarks and ≈1100 programs
After all, facts are facts,
and although we may quote one to another with a chuckle
the words of the Wise Statesman, 'Lies--damned lies--and statistics,'
still there are some easy figures the simplest must understand,
and the astutest cannot wriggle out of.
Leonard Henry Courtney, 1895

Benchmarking programming languages?
How can we benchmark a programming language?
We can't - we benchmark programming language implementations.
How can we benchmark language implementations?
We can't - we measure particular programs.
