Benchmarks
hello - output hello world to measure kernel calls add - run integer adds by linear fibonacci of 40 call - exercise calling by recursive fibonacci of 20 noop - a baseline that does nothing loop - just counts down, from 1M
Loop, Hello, add and call run 1M , 50k, 10k and 100 respectively, to minimize startup impact.
C was linked statically as dynamic linked influences times. Output was sent to /dev/null, so as to measure the calling and not the terminal. Also output was unbuffered, because that is what rubyx implements.
Results
Results were measured by a ruby script. Mean and variance was measured until variance was low, always under one percent. Noop showed that program startup is a factor, so all programs loop somewhere from 1M to 100, depending on how intensive.
The machine was a virtual arm (qemu) run on a acer swift 5 (i5 8265 3.9GHz), performance roughly equivalent to a raspberry pi. Results (in ms) should be seen as relative, not absolute.
