Good question. This is on the same machine, average of five runs
after warming the cache with one run:
time emacs --batch --eval '(message "Hello")'
Kubuntu 12.10 x86_64 : 0.026 s
Windows XP SP3 32 bits: 0.240 s
Bootstrapping compiles ~1400 el files. The difference on process startup
accounts for >5 minutes. And that's only for byte-compiling. Add
invocations to gcc, make, cmd, fileutils, etc.
Still, most of the difference on bootstrap time is unexplained. Maybe
it's the filesystem, maybe Emacs is super-optimized for GNU/Linux and
not so much for MSWindows...
