That said, I didn't remove the wchart cache (though I tried some tricks to avoid it), so it's possible that once that's gone we'll see an avoidable regression here, but on its own this doesn't contribute much.

Could you please test PR 2599 on Windows? It makes PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() not filling the wchar_t cache. If there is a significant regression in any benchmark or small regressions in several benchmarks we can consider to continue to fill the cache in these function and to preserve the cache in future. Otherwise I'll merge the PR as is.
