On the other end of the spectrum, really poorly performing code can affect development, testing and delivery times which eats developer time as well. Some developers or testers might sit oh welling waiting for 1hr job to finish when 1 day of development time could turn that job into a 5min run. That kind of optimization pays for itself before it even makes it to production.

Adding poorly performing code is a bit like pissing in a swimming pool.

A little bit is ok. If you have to. But too much of it and there's no way back other than draining the pool and starting again.
