Comment (by Adam Johnson):
Yeah, there’s no bug here. 30 times slowness is about right for a
Rust/Python comparison. Also the benchmark is minimal and unrealistic, the
margin should be less (maybe not much) for a typical template that has far
fewer nodes.
This would be an interesting forum discussion - not a bug in the bug
tracker. I’d be interested in seeing more. And if you want to get into
optimizing specific parts of the template engine, I’d be up for reviewing
some PRs. My recent work on the system checks may be a nice guide:
