So this program is writing the first byte of buf, 8192 times. Let's
call this program an apple.
Did you mean:
write(1, buf+i, 1) ?

(Did you try running this program - the second param
to write should be an address, not a size_t)?
This program is filling buf with binary zeroes twice, then
writing one random byte once. Let's call this program
an orange.
What exactly are you trying to compare here?
