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.

Comparison with ruby, not really for speed, just to see how much leeway there is for our next layer. Ruby startup time is 1,5695 seconds, which we'll subtract from the benches
