OSH Parser Performance
We time $sh -n $file for various files under various shells, and repeat then
run under cachegrind for stable metrics.
Source code: oils/benchmarks/osh-parser.sh
Raw files
Summary
Instructions Per Line (via cachegrind)
Lower numbers are generally better, but each shell recognizes a different
language, and OSH uses a more thorough parsing algorithm. In thousands of
"I refs".

Average Parsing Rate, Measured on Two Machines (lines/ms)
Shell startup time is included in the elapsed time measurements, but long files
are chosen to minimize its effect.
