I totally disagree, I think that era has been over for the last 20 years.
I keep coming back to a talk by Daniel J. Bernstein, that the assumptions computer science teaches about performance are wrong. His claim is for real programs most code is ice cold and a tiny percentage is hot. And that's getting worse not better as time goes on.
What important is; correctness, latency, compile time. Not raw speed.

In my experience that claim is very true before you fire up your profiler. But once you've optimized your program for a bit the profile gets a lot flatter.
