I played with the benchmark and the extra delay was not significant, maybe 20ms for a substantial page? I profiled the code and did not find it doing anything particularly wrong. However it uses generators to build the page lazily from fragments at runtime, whereas jinja gets a boost from “compiling” them somehow. I believe one could prerender the static parts of the page and get most of the speed of jinja, but the improvement still won’t be noticeable unless the project is very performance sensitive.
