There's no such thing as optimal timeout settings IMHO. The fact that your servers are sitting in the same datacenter is sonething you need to take into account, but also the behavior of your backends. For example, if you know that your backend will stream results immediately you might want to lower the fbto, and if your backends tend to precompute the response before sending it you might want to lower the bbto instead. If you are not familiar enough with the backends implementation details, the best course of action is probably to be conservative and measure the response times to find out the expected responsiveness from the backends. > Oh and heck.
