Hello, we have a client-server application which establish a long-living TCP connection and generates a lot of small request-response packets which need to be processed very fast. Setting TCP_NODELAY on sockets speed things up to about 3 times.
Not I want to put a haproxy in the middle so it balances traffic between several servers. Something like defaults mode tcp frontend shard0-front bind *:9000 default_backend shard0-back backend shard0-back server srv1 srv1:3456 check server srv2 srv2:3456 check In such configuration application slows significantly. I suspect that setting frontend's and backend's sockets option TCP_NODELAY would help as it did without haproxy involved. Is there any parameter which allows me to set TCP_NODELAY option? Thanks!
