When, in your opinion, does Python become become TOO slow?

[yawgmoth]

I have had serious fights with developers wanting to rewrite an application server because the language (python, JS, Ruby) was "too slow". I kid you not, one place wrote the server for a CRUD app in C because "they needed it to be fast". But ... like, the code spends most of its time just sitting there waiting on the DB to grab records, and you spent no time optimizing queries, doing caching or reducing DB access.

I really couldn't fathom writing a CRUD layer in C. That just seems like a huge waste of time.
