The mystery still stands.
I suggest to separate variables here, and time the byte compilation
alone. Try this:
cd lisp
find . -name "*.elc" -delete
make compile
and time the last command.
With the current trunk, you can do "make -j6 compile" instead of the
last command, and it should be about 3 to 4 times faster.
