Does it show about 200 ms like above, or about 20 ms like firebug showed?
I suspect that the 200 ms is due to the ssl session being established
afresh for each request, while firebug is piggy-backing on a previous
(You could test this by starting firebug and making sure that the
very first https query is for this url, and seeing how long it takes.)

Untested by me, but: do you see any difference when you include the
configuration at http://nginx.org/r/keepalive ?
That might allow re-use of the ssl session across http requests.
