Two analysts at Exxtol Petrol, Ltd., Log Jam and Bot L. Neck, are having an argument. They are comparing an $\mathrm{M} / \mathrm{M} / 1$ system with mean arrival rate $\lambda$ and mean service rate $2 \mu$ (we assume $\lambda<2 \mu$ ), with an $\mathrm{M} / \mathrm{M} / 2$ system with mean arrival rate $\lambda$ and mean service rate $\mu$ for each server. Log says the $M / M / 2$ system is best because
$$
W_{q_{M / M / 2}}<W_{q_{M / M / 1}} .
$$
Bot responds that Log has it all wrong because
$$
W_{M / M / 1}<W_{M / M / 2},
$$
and therefore, the $\mathrm{M} / \mathrm{M} / 1$ system is superior. Who is right? Note that the two systems have equal capacity; Log and Bot are comparing a single-server system to a double-server system with half-speed servers.
