Unfortunately, it doesn't work the way it may seem from the snippet you posted.Keep in mind, the physical server itself isn't under heavy load at all, and isn't the root cause of load problems.When you start a Tor service, it propagates through the authoritative directory servers, and then to the other directory services. The authoritative directory servers can only promote one hidden service instance at a time. The process may take in excess of an hour, not the milliseconds switching time needed for load balancing. Also, as far as your browser is concerned it's a new session, so whatever you were doing on the site before the change is lost.Tor doesn't scale like the normal web, and you can't load balance multiple servers for greater throughput.The slowness of the site has to do with node congestion due to heavier traffic and the high number of simultaneous connections than the system is designed to handle.
