It says that MS Windows is ~80% slower than GNU/Linux at running emacs
with for evaling a simple expression :-)
Serioulsy, though, Emacs does quite a few things at startup. My day to
day experience is that GNU/Linux efficiency at starting processes make a
difference when running lots of instances of short-lived programs, as,
for instance, a compiler test suite. Years ago, I worked on MS-Windows
native and on a virtualized Debian install: running the test suite for
the compiler I was working on required more than twice the time on
MS-Windows than on the Debian virtual machine.
As for emacs build times, the startup time is small enough to not make
it all that relevant while running >1000 times emacs.exe for compiling
all the .el files.
Still, I don't understand how your i7 is 90% slower than my old Q6600,
running the same OS. IIRC you mentioned that your build is unoptimized.
Mine is with default configuration, which defaults to -O2.
