Larry:
The rest of the code is numerical so it will not change by much the fact that d cannot get back the huge launching time. At the microsecond level(even nano) it counts because of electrical consumption, size of hardware, heat and so on.
Have you benchmarked the D code without starting the current d-runtime (without GC)?
Is a starting time of around 0.015 seconds on an old PC is a huge one? I think no one has worked a lot in decreasing this tiny time. If you care for such time, D being open source, you can take a look at the runtime starting code.
