Just curious, but were these tests run with mmap(), or NO_MMAP?

Both with NO_MMAP=YesPlease.

I wonder what the difference is between NO_MMAP=Yes and NO_MMAP=
on Windows.

Cygwin:

	$ time git-rev-list next >/dev/null

	real    0m0.812s
	user    0m0.358s
	sys     0m0.203s

	$ time git-rev-list next >/dev/null

	real    0m0.797s
	user    0m0.358s
	sys     0m0.234s

	$ time git-rev-list next >/dev/null

	real    0m0.845s
	user    0m0.390s
	sys     0m0.265s

and

	$ time git-log next >/dev/null

	real    0m2.094s
	user    0m0.718s
	sys     0m1.077s

	$ time git-log next >/dev/null

	real    0m2.078s
	user    0m0.718s
	sys     0m1.062s

	$ time git-log next >/dev/null

	real    0m2.124s
	user    0m0.796s
	sys     0m1.046s

IOW, the numbers are slightly worse (!) than with mmap().

MinGW does not even have mmap().
