To quote http://marc.info/?l=haproxy&m=132173719731861&w=2, which I discovered via searching http://marc.info/?l=haproxy&w=2&r=1&s=nagle&q=b: 'the "http-no-delay" option [...] forces TCP_NODELAY on every outgoing segment and prevents the system from merging them.' Willy warns, however: "Doing so can increase load time on high latency networks due to output window being filled earlier with incomplete segments and due to the receiver having to ACK every segment, which can lead to uplink saturation on asymmetric links (ADSL, HSDPA)."
