# 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
|
|
typed 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
