Add rinohtype benchmark?

[brechtm]

Do you think it would be interesting to add a rinohtype benchmark to pyperformance? rinohtype is a pure-Python (PDF) document renderer with a limited set of dependencies (unless you want to use it as a Sphinx builder, which pulls in many more).

Performance was my main worry when implementing rinohtype in Python. While rendering speed is acceptable, I think it is still much slower than TeX for example, so it can benefit from a faster CPython or PyPy. I haven't benchmarked recently, but last time I tested PyPy it managed to outperform CPython by 25%.

If you think it would be a worthwhile addition to the set of benchmarks, I can provide one.
