As I remember, Bevin Brett reported similar results with the DEC Ada compiler.
The problem with taking this at face value is that there's no way to tell if
this might be due to the effects of the language, more effort being spent on
optimizing Ada (at the time it presumbably had more military users than the C
compiler), utilizing lessons-learned from implementing the C compiler earlier,
or the superior brain-power of Bevin and everyone else involved with the Ada
compiler.

Still, its a nice piece of evidence to have in one's pocket when those "Ada is
slow" threads pop up.
