Hi!

Please note that ab itself a huge bottleneck and it gives you zero
information about nginx performance. As you can see you hit the 100% CPU
-what comes from ab load-.
I realized that during performance testing, all what I can tell you: use the
httperf instead if you have a chance.
(do not forget to modify the FD_SETSIZE to higher value)

Regards,
Istvan
