Well, I found a page that show how to increase backlog in several operating 

In Linux one could say:
# sysctl -w net.ipv4.tcp_max_syn_backlog="2048"

I tested with 800 connections and it worked although not blindingly fast as 
I hoped, but without errors. 1000 connections gave timeouts (with default 
10 second timeout) but otherwise ok.
