Your spirit of healthy scepticism is admirable but what these
tests compare is not so much the time it takes to create a file
with ">" vs touch(1) than the time it takes to create a process
relative to the time it takes for the shell to iterate through
a for() loop.

Try "seq 0 9999 | xargs touch" (3 process creations instead of
10,001). It will almost certainly be even faster than the ">"
version.
