We consider polling systems with random setup times, and show that if setup times are reduced in the convex ordering sense, then waiting times, work loads, and queue sizes will be reduced in the usual stochastic sense. We also show that the joint distributions of various performance measures across time are invariant under shifts in setup times as long as the net shift is zero.
