I can't repeat problem with my nginx 1.5.9

* HTTP 1.1 or later with persistent connection, pipelining supported
< HTTP/1.1 200 OK

Request time in logs - 2.087

1. Do you have the timer_resolution directive in you config? Try to remove it 
for test.

2. Try to run
curl --limit-rate 100k
to be sure, that request time >> 1 ms.

Try to analyze debug log:
