i think percentages with +/- is best otherwise it becomes an issue of which way you look at it. 1,33 or inverse 0.75 looks like a third one way and a quarter the other

Benchmarks
loop - program does empty loop of same size as hello hello - output hello world (to dev/null) to measure kernel calls (not terminal speed) itos - convert integers from 1 to 100000 to string add - run integer adds by linear fibonacci of 40 call - exercise calling by recursive fibonacci of 20
Hello and puti and add run 100_000 iterations per program invocation to remove startup overhead. Call only has 10000 iterations, as it much slower
Gcc used to compile c on the machine soml produced by ruby (on another machine)
Results
Results were measured by a ruby script. Mean and variance was measured until variance was low, always under one percent.
The machine was a virtual arm run on a powerbook, performance roughly equivalent to a raspberry pi. But results should be seen as relative, not absolute.
