200ms typically sounds like a TCP delayed ACK issue. Could you please test if adding "no option tcp-smart-accept" to the frontend fixes the issue ? If so, I'd be very much interested in getting a network capture of a whole request (please use tcpdump -s0 to get full packets). It might be possible that curl uses an "Expect: 100-continue" header and that we don't disable the delayed ACK when sending it (just a suggestion, I'm not saying this is what happens).
