Obviously not in any way an answer to the question asked.

edit: Please provide a better response than downmods.

Go actually check the things pcwalton mentioned instead of complaining.

Please provide comparison measurements of the things pcwalton mentioned.

Just a URL to published comparison measurements would be so much more interesting for anyone interested in Rust, than downmods.

How about some measurements made with rustc 1.0.0?

(There seem to have been plenty of breaking language changes in the last 6 months.)

(The "faster" bit isn't important; various reasons might have made C++ slower than Rust for this, but what is important is that perf was comparable)

Do you think a 100 line ray tracer is any more "correlated with real-world performance" than 100 line benchmarks game programs?

What I questioned was Rusky's technical-sounding but apparently unsupported claim that "the benchmarks game's results are not very correlated with real-world performance." For Rusky to know he'd need some kind-of "real-world performance" measurements and a correlation coefficient - neither of which have been shown.
