Slow connections

I am seeing a good amount (1/100) of connections to varnish (from 
haproxy) taking 3 seconds. My first thought was the connection backlog 
but somaxconn and listen_depth are both set higher than the number of 
connections. Anyone have any suggestions on how to track down what is 
causing this or settings I can use to try to aleviate it?
