Sumario:Expected b-tagging performance in ATLAS during LHC Run-2 is presented together with results of commissioning studies of early Run-2 data. The performance of b-tagging is expected to be significantly improved in Run-2 thanks to the addition of the new pixel detector layer and updates in the tracking and b-tagging algorithms. First commissioning studies of data showed promising agreement with Monte Carlo simulation.
