thats most of the benchmarking

strange about the puts in soml, hard to see where a factor of 10 would
come from

+# 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,
+usually 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.
