I've tried that now, and I observe that the "real" component varies
between 145 and 200 ms (without decreasing or increasing tendency;
it's kinda random).
I don't understand such big difference with the previous measure.
In any case, the total bootstrap time keeps about the same: about 15 min.

I don't know what's the best way to measure execution time from a
cmd.exe shell. I've written this script:
@echo Start %time%
@C:\emacs\trunk\bin\emacs --batch --eval '(message "Hello")'
@echo End %time%
And I get this output when I run it:
Start 21:33:04.25
Loading macroexp.elc...
End of file during parsing
End 21:33:04.42
