What the option does is close the connection between the proxy and the backend so that HAProxy will analyse further requests instead of just forwarding to the already established connection.
To be fair, I don't know what nginx does - whether connections are kept open or shut down - so I'm not sure that it'd be a fair comparison.
Also interesting are the HAProxy built in SSL times. I'm surprised they're so slow. Perhaps the cipher is also the culprit. The cipher can also be specified in HAProxy.
The `http-server-close` option did not change anything. But by adding the ciphers it was able to squeeze out the same performance as Nginx. I'll update the tests accordingly. Thanks for the heads up!.

It would be interesting to see the difference with HAProxy if this line was removed: https://github.com/observing/balancerbattle/blob/master/hapr...

Thanks for testing these. I'm glad HAProxy passes muster with regards to SSL as we're currently moving to 1.5-dev18 from apache SSL offloading.
I'll re-run the test with the advised changes and see if the performance improves.
