In some past experiences, firewall can add a small overhead in connection establishment. If you're using iptables, you can try disable it for a second, test the connection establishment to check if the overhead is being added by the firewall and enable that afterwards.
for sure not, iptables handles thousands of new connections per second with no measureable overhead, especially on 127.0.0.1 which has typically a early ACCEPT rule
