Ah, cool, got it - thanks! My reading of this is that a good few of the benchmarks are coming out firmly in PyPy's favour, but a number of them are still in CPython's favour (including "telco" where PyPy is staggeringly worse for some reason). But a number of the "PyPy is worse" benchmarks are ones that seem less significant - for instance, SQLAlchemy seems to be slower, but if you're using SQLAlchemy, you're probably more concerned about database performance than the CPU cost inside Python. > For some reason the "permalink" feature does not let me share that > configuration. Yeah, there seem to be some issues with that page. The first time I loaded it, the chart was entirely broken - I was looking for the "show chart" button, but it was just that it had errored out for some reason. Still, at least the data's there. > I guess we could switch to emphasizing python3 on the front page, help > in updating and reconfiguring Codespeed [1] would be awesome. If only I had infinite time in the day, I'd love to dive in and help out... It definitely would be worth at least having a quick summary and link somewhere.
