> A big difference is that HAProxy's main balancing algorithm is "fair" I don't think that's really true - haproxy has lots of load balancing modes, none of which are called "fair". It's also very unclear what you'd mean by "fair" in this context. Least connection? Maybe, but with a traffic pattern with large volumes of very short-lived requests, least connection actually won't be very fair at all, and will end up loading some servers more than others. Roundrobin isn't really "fair" either, if you have a mix of short and long requests.
