response times and network io

i am performing some httperf tests against apache and nginx. something i
noticed that piqued my interest were the consistency of response times
(0.4 ms each run regardless of number of request, much lower than apache
in all cases) and network I/O (consistently higher than apache
regardless of number of request). it also uses less cpu than apache and
doesn't nearly drive up the load.
are these normal results? is there a mechanism in nginx that keeps the
response times low and consistent? also, is it normal that it uses more
network I/O? if so, what is the cause? to me it would seem like that it
uses more bandwidth to respond to the same number of requests which
please correct me if i am wrong. i am just trying to understand the core
differences in how nginx works in comparison to apache and why i would
see these performance differences.
thanks for the help.
