Any backend loadbalancing solution depends on having multiple backends, if your legacy application can only handle 1 connection and you add another 9 you still can handle only 10 concurrent users.
nginx can handle thousands of concurrent users and pass them on to a backend, so in your case you are going to get a very large que.
Can your legacy application handle requests on different ports? or is it just listening on more ports with the same limit?
Maybe you could move the functionality of your legacy application to Lua and just let it deal with data.
