Query: Light traffic behavior under the power-of-two load balancing strategy:
  The case of heterogeneous servers   We consider a multi-server queueing system under the power-of-two policy with
Poisson job arrivals, heterogeneous servers and a general job requirement
distribution; each server operates under the first-come first-serve policy and
there are no buffer constraints. We analyze the performance of this system in
light traffic by evaluating the first two light traffic derivatives of the
average job response time. These expressions point to several interesting
structural features associated with server heterogeneity in light traffic: For
unequal capacities, the average job response time is seen to decrease for small
values of the arrival rate, and the more diverse the server speeds, the greater
the gain in performance. These theoretical findings are assessed through
limited simulations.
