I was reading this article. It has the following paragraph.

And did Scala turn out to be fast? Well, what’s your definition of fast? About as fast as Java. It doesn’t have to be as fast as C or Assembly. Python is not significantly faster than Ruby. We wanted to do more with fewer machines, taking better advantage of concurrency; we wanted it to be compiled so it’s not burning CPU doing the wrong stuff.

I am looking for the meaning of the last sentence. How will interpreted language make the CPU do "wrong" stuff ?
