The last time I did a comparison was with Mach. I tried
to compare the sources required to make a MIPS kernel with
nothing but a serial console as a device. I just counted lines
with semicolons, i.e., 'grep ';' | wc -l'. I really couldn't
configure Mach to do that without a Unix personality
so I didn't count that. It was still an astounding difference,
on the order of 10 to 1.
If someone feels like doing it for Linux, Unix, whatever,
lets just come up with a benchmark configuration. How
about
x86
one vga card (nvidia tnt2)
ps/2 mouse
ethernet (intel 82557)
ip stack
keyboard
no disk, no local fs
Build the minimum kernel that lets you run enough cruft
to start a window system and get work done. Assume a remote fs
(or not if you think that's unfair).
See how many ; lines that takes.
This doesn't mean that they have equal function. However,
its the only objective comparison I can come up with.
What the results would imply is pretty subjective. If
one group thinks memory is free, they might require all
sorts of stuff to exist in a minimal configuration. Unless
the size of the compared systems is orders of magnitude
different, all you're really comparing is design choices
made by the designers for what they thought a typical
configuration would be.
