Well, yes. But look at the SPEC build times. Those have been
going up steadily for both SPEC95 and SPEC2000:

Bootstrap times seem steady (the graph shows a huge peak in
mid-Dec, that's when I started bootstrapping all front-ends
instead of just C and Fortran).

On the optimization side, things are indeed looking a bit better.
Particularly for Fortran.
