  We study the efficiency of synchronization in ensembles of identical coupled
stochastic oscillator systems. By deriving a chemical Langevin equation, we
measure the rate at which the systems synchronize. The rate at which the
difference in the Hilbert phases of the systems evolve provides a suitable
order parameter, and a 2--dimensional recurrence plot further facilitates the
analysis of stochastic synchrony. We find that a global mean--field coupling
effects the most rapid approach to global synchrony, and that when the number
of "information carrying" molecular species increases, the rate of synchrony
increases. The Langevin analysis is complemented by numerical simulations.
