Abstract
Being interested in how a strongly coupled system approaches asymptotic freedom, we reexamine existing precision lattice QCD results for thermodynamic properties of the gluon plasma in a large temperature range. We discuss and thoroughly test the applicability of perturbative results, on which grounds we then infer that the pressure and other bulk properties approach the free limit somewhat slower than previously thought. We also revise the value of the first nonperturbative coefficient in the weak-coupling expansion.
