Here's my result on my own site:

Not exactly fast (cpu constrained - kvm instance of 1 core/thread
e3-1270 cpu, 512MB ram, debian linux 6) but certainly completed all
requests without fail. 15 php5-cgi instances ran through supervisord
in tcp mode. There are quite a bit plugins installed, too (but no
wp-cache of some kind).

No tweaking at nginx side, some timeout and limit increase on php side.
