This note describes a simulation experiment involving nine exponential queues in series with a non-Poisson arrival process, which demonstrates that the heavy-traffic bottleneck phenomenon can occur in practice (at reasonable traffic intensities) as well as in theory (in the limit). The results reveal limitations in customary two-moment approximations for open queueing networks.
