The problem is that you want to control not just for header files but
for the general time the system takes.

I think it's patently obvious that the Plan 9 kernel itself is much
more tightly coded than either BSD or Linux.

It would be *even better* if the Plan 9 kernel were being compiled
with an optimizing compiler.

So the real test of compile speed is:

Compile one system with 8c, and then use the 8c compiler.

Compile the *same* system with GCC -O3, and then use GCC with no -O.
