Your test is extremely misleading. On one system I manage, the page size
is 64K, and practically every executable is at least two pages. Guess
what? fork() takes a *noticeable* amount of real time, simply because
the machine spends so long loading from disk. But with several users
running programs from several different disks, everything overlaps
nicely and the total time spent is relatively small. I suspect the same
is true of the systems you test---every fork() takes 30 or 50 ms, but
many of them can overlap at once.
