no, the distribution happens all the time. To make it simpler to understand, imagine that you have weight=1 for all servers. Haproxy will then try to balance the established connections so that all servers have the same number. Now if one server has weight 2, haproxy will try to load it with twice the number of connections as the first one. And so on... That's why leastconn is normally used with long-lived connections (eg: RDP, LDAP, SQL, ...). Willy
