[erlang-questions] file:sendfile/2 benchmarks?

I am experimenting new sendfile(2) options
for FreeBSD 11 on OTP 19.0.2.

While the new options do not seem to break the function,
I cannot measure the possible performance gain yet.
Is there any good benchmark tool for measuring
file:sendfile/2 performance?
(I think Yaws uses Erlang VM file:sendfile/2 already)

Note that Tuncer Ayaz gives the original idea
on an earlier implementation of OTP as:

Nginx's summary for FreeBSD 11 sendfile(2) features (with Netflix):

And for those who want to test my patch, it's there at:
