Measured : Which programming language is fastest?
My question is if anyone here has any experience with simplistic benchmarking and could tell me which things to test for in order to get a simple idea of each language's general performance?
There's more than one right
answer.
For the fastest
contributed programs —
The box plot charts show a visual summary of the data: medians, dispersion, skew.
For a simple program —
The current Ruby mandelbrot multicore programs are 7x faster than this simple Ruby transliteration and the exhaustively-optimised + multicore + vector-instruction C programs are more-like 25x faster than this simple C program.

Transliterations are not necessarily idiomatic
. When the Ruby #2 and Python #2 programs are most idiomatic
they are furthest from identical — are they similar-enough to be comparable for your purposes? (The Python #2 program uses a built-in complex-number type.)
The slightly-moderately-highly-wildly ("I spent two weekends on this") optimised mandelbrot programs are not identical — does that matter for your purposes? And [pdf] As fast as C or As fast as SSE and AVX?
