I think HAProxy and DNS round-robin solve different kinds of scalability issues: - the application running behind the hidden service is taking too much ressources for a single node. Something like HAProxy can help split the application on multiple nodes, but all traffic still go through a single node. - the network bandwidth that a single node can have or the number of connections it can handle is not enough. A solution like HAProxy doesn't help, because everything still has to go through a single node. I think the DNS round-robin is used to solve this kind of problem. _______________________________________________ tor-dev mailing list [email protected] https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-dev
