I can believe that, but wonder if it needs to be so.
For example, in my (limited) experience, you have to draw the boundary between what's in Ruby and what's in C/C++ intelligently. If you're still doing most of your computation in C on Ruby Arrays and Hashes, you're not going to get much of a performance win at all.
