I just succeeded in modifying the wrk source code so that is connects with multiple servers rather than just the one. I can confirm that it gets the same throughput as with one host. So I take back my comments about there being a difference between one host simulating many being different to an actual test with many clients. There must be a problem with my epoll implementation because the modified wrk codebase works just fine.
