  We present the results of a large-scale numerical study of the equilibrium
three-dimensional Edwards-Anderson Ising spin glass with Gaussian disorder.
Using parallel tempering (replica exchange) Monte Carlo we measure various
static, as well as dynamical quantities, such as the autocorrelation times and
round-trip times for the parallel tempering Monte Carlo method. The correlation
between static and dynamic observables for 5000 disorder realizations and up to
1000 spins down to temperatures at 20% of the critical temperature is examined.
Our results show that autocorrelation times are directly correlated with the
roughness of the free-energy landscape.
