to make smaller binaries with larger integer heaps also ran some benchmarks to see if it makes a difference at least the binaries are smaller, calling also faster

# 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.
