Amos' comment is accurate, and the SmpScale imbalance does not apply to this case. I was confused by the "workers" terminology used in this thread instead of "instances". To me, "workers" imply SMP, but the "Frontend Balancer Alternative 1: iptables" setup discussed in this thread uses essentially independent Squid instances rather than identically configured SMP workers. Those independent instances can be implemented using an SMP configuration with a workers directive, but I do not consider such an implementation a supported use case (some do). Sorry for the noise, Alex.
