“A lot of the time will be spent waiting for the database or other IO, so blazing fast templates are not absolutely necessary.” I'm not sure I agree with this philosophy. It's not like you can render the template in parallel. If your database/other IO is slow and you're already taking 200ms on your templates, it may be the difference between a happy user and a sad one.
