Hi,David Pollk! Nginx only comes with a round-robin balancer and a hash-based balancer, so if a request takes a while to load, Nginx will start routing requests to backends that are already processing requests -- as a result, some backends will be queueing up requests while some backends will remain idle. You will get an uneven load distribution, and the unevenness will increase with the amount of load subject to the load-balancer.
Haproxy as a LB can: 1: Plenty of load-balancing algorithms, including a "least connections" strategy that picks the backend with the fewest pending connections. Which happens to be just what we want. 2: Backends can be sanity- and health-checked by URL to avoid routing requests to brain-damaged backends. (It can even stagger these checks to avoid spikes.) 3: Requests can be routed based on all sorts of things: cookies, URL substrings, client IP, etc. So, I use nginx + haproxy + tomcat(jetty).
